Alkaline Fuel Cells: How the Oldest Fuel Cell Is Finding Its Market in Resilient Power
Updated: 4 days ago
Executive summary. The alkaline fuel cell powered the Apollo spacecraft and then spent four decades as a footnote while proton exchange membrane and solid oxide technologies took the headlines. In 2026 it is back, and for a practical reason: it does not need platinum. Strategic Revenue Insights estimates the global alkaline fuel cells market at USD 260.00 million in 2025, rising to USD 615.51 million by 2035 at a 9.00 percent compound annual growth rate. The growth is concentrated in stationary and backup power, where the technology's tolerance for low-purity hydrogen and ammonia, its low-cost catalysts and its long operating life suit the telecom towers, utility substations, data centres and off-grid sites that are replacing diesel generators. The companies that will capture it are the ones that treat the alkaline fuel cell as a resilience product with a fuel-supply strategy rather than as a laboratory technology. This article sets out five lessons from the developers and early adopters moving first, with takeaways for strategy, technology, fuel, go-to-market and revenue.
The structure of that growth matters more than the headline. Strategic Revenue Insights' Alkaline Fuel Cells Market research finds that hydrogen-fed alkaline fuel cells are the largest type segment while direct alcohol alkaline cells are expected to grow fastest, that anion exchange membrane cells form the technology bridge between the two, that stationary power is the largest application ahead of transportation, portable power and space and defence, that utilities are the largest end-user group, and that Asia Pacific is both the largest and the fastest-growing region. The research identifies demand for clean energy, government policy support, the focus on energy security and research investment in efficiency and cost as the drivers, and the high cost of fuel cell technology, competition from solar, wind and batteries, policy volatility and supply chain disruption as the restraints.
The hydrogen context sets the pace. The International Energy Agency's Global Hydrogen Review 2025 reported that global hydrogen production reached almost 100 million tonnes in 2024, that less than 1 percent of it was low-emissions, that low-emissions production grew 10 percent in 2024 and was on track to reach 1 million tonnes in 2025, and that projects which are operational, under construction or have reached a final investment decision could lift low-emissions output fivefold to 4.2 million tonnes a year by 2030. The agency also cut its estimate of the announced 2030 pipeline from 49 to 37 million tonnes a year after a wave of cancellations. The signal for fuel cell developers is that hydrogen will be available but not cheap or ubiquitous, which favours technologies that can run on whatever hydrogen, or ammonia, a site can get.
Why the Alkaline Fuel Cells Market Is Entering a New Phase
Three structural forces are converging.
Catalyst cost has become the deciding variable. Proton exchange membrane fuel cells depend on platinum-group metals; alkaline cells can use nickel, silver and other non-precious catalysts because the alkaline environment is kinder to them. As fuel cell deployment scales, the cost and supply risk of platinum become a structural disadvantage, and SRI's research names the high cost of fuel cell technology as the primary restraint. The alkaline chemistry is the lowest-cost route around it, and research progress has been rapid: a January 2026 paper in ACS Energy Letters reported a platinum-group-metal-free anion exchange membrane fuel cell with a record peak power density of 515 milliwatts per square centimetre on hydrogen and oxygen and 281 on ambient air.
Resilient power has become a procurement category. Grid instability, extreme weather, data centre growth and the expansion of mobile networks into remote areas have made backup and off-grid power a budgeted purchase for utilities, telecom operators and critical facilities, and diesel generators are increasingly constrained by emissions rules, fuel logistics and noise. SRI's research names energy security and independence as a driver and stationary power as the largest application; the alkaline fuel cell's long life, quiet operation and fuel flexibility make it a candidate for the segment of that market where diesel is no longer acceptable. The same resilience logic is driving the artificial intelligence investment that utilities are making in grid infrastructure.
Ammonia and low-purity hydrogen have opened the fuel supply. Alkaline cells tolerate impurities that poison proton exchange membrane cells, which means they can run on industrial by-product hydrogen and on hydrogen cracked from ammonia, a fuel that is already shipped and stored worldwide. AFC Energy's demonstration of a 500 kilowatt-electric alkaline system on untreated waste hydrogen at an Air Products plant in Germany, and GenCell's ammonia-fed systems for off-grid telecom, are the commercial expressions of that advantage. SRI's research names supply chain disruption as a restraint; fuel flexibility is the technology's answer to it.
These forces explain SRI's forecast of a market that more than doubles between 2025 and 2035, with growth concentrated in stationary and backup power, in utilities and telecom, and in Asia Pacific.
Five Lessons From the Companies Moving First
The developers, component suppliers and early adopters converting the alkaline fuel cell from a heritage technology into a resilient power product share a recognisable pattern. We have distilled it into five lessons, each followed by a takeaway for a specific leadership function.
Lesson 1: Pick the Application Where Your Weakness Does Not Matter
The alkaline fuel cell has a well-known weakness: carbon dioxide in air reacts with the alkaline electrolyte and degrades performance, which is why the technology lost the automotive race to proton exchange membrane cells. The companies moving first have stopped fighting that weakness and chosen applications where it is manageable: stationary systems with air scrubbing, sealed or controlled environments, and anion exchange membrane designs that are more tolerant of ambient air. SRI's research identifies stationary power as the largest application and utilities as the largest end user for precisely this reason; the technology fits where the system is fixed, the fuel is stored on site and the operating conditions can be controlled.
That choice changes the competitive set. In stationary backup the alkaline cell competes with diesel generators, lead-acid and lithium batteries and proton exchange membrane systems, and it wins where runtime is long, platinum cost matters, fuel purity is variable and maintenance visits are expensive, which describes remote telecom towers, substations and off-grid industrial sites. The lesson from the companies named in SRI's research, AFC Energy, GenCell, Cummins through Hydrogenics, Ballard, Plug Power, Doosan, Panasonic, Toshiba, Bloom and FuelCell Energy among them, is that the alkaline chemistry is a niche technology with a large niche.
"Every fuel cell chemistry has a weakness. The companies that succeed are the ones that choose the application where their weakness is irrelevant and their strength is the whole story."
Takeaway on strategy. Define the product around stationary, controlled-environment applications where long runtime, non-precious catalysts and fuel tolerance outweigh air sensitivity. Target the segments where diesel is being regulated out and batteries cannot deliver the runtime: remote telecom, utility substations, critical facilities and off-grid industry. Avoid applications that play to the strengths of competing chemistries.
Lesson 2: The Catalyst Is the Cost Advantage, So Protect It
The absence of platinum is the alkaline cell's structural advantage, and the companies moving first have built their technology roadmaps around widening it: nickel and silver catalysts, durable anion exchange membranes, and stack designs that extend life and reduce balance-of-plant cost. SRI's research names research and development investment in efficiency and cost as a driver, and the 2026 laboratory results on platinum-free anion exchange membrane cells show how quickly performance is improving.
The commercial task is to translate laboratory power density into field durability. Backup and off-grid customers buy on total cost over ten to twenty years, which depends on stack life, maintenance intervals and electrolyte or membrane replacement cycles as much as on upfront price. The companies moving first publish durability data, offer performance guarantees and design for field serviceability, because the cost advantage of a cheap catalyst is lost if the stack must be replaced every few years.
Intellectual property matters here. The membranes, catalysts and electrolyte management systems that make alkaline cells durable are the defensible assets, and the companies that own them will set the terms for licensing as the market scales.
Takeaway on technology. Prioritise durability over peak performance in the development roadmap, publish field data and back it with guarantees, and protect the catalyst, membrane and electrolyte intellectual property that underpins the cost advantage. Measure progress in cost per kilowatt-hour delivered over the system's life, which is the metric the stationary customer uses.
Lesson 3: Sell a Fuel Supply, Not Just a Fuel Cell
A fuel cell without fuel is a sculpture, and the stationary customer's first question is where the hydrogen will come from. The companies moving first have answered it by designing for the fuels that are actually available: ammonia, which has a global supply chain and can be cracked on site; by-product hydrogen from industrial processes; and compressed hydrogen delivered where the infrastructure exists. The alkaline cell's tolerance for impurities is what makes this flexibility possible, and the companies that have packaged the cracker, the storage and the fuel supply contract with the system have removed the customer's biggest objection.
The International Energy Agency's figures make the point: low-emissions hydrogen will grow fivefold by 2030 on committed projects, but it will remain a small fraction of total supply, and many announced projects will not be built. SRI's research names supply chain disruption and policy volatility as restraints; a product that depends on a hydrogen pipeline that may never arrive is exposed to both. A product that runs on ammonia delivered by truck is not.
Fuel supply is also a recurring revenue line. The companies that supply the fuel, or arrange it, earn on every kilowatt-hour the system produces, which converts a capital sale into a long-term relationship.
"The customer is not buying a fuel cell. The customer is buying ten years of power at a site where the grid cannot be trusted. Whoever guarantees the fuel wins the contract."
Takeaway on fuel strategy and partnerships. Design systems for ammonia and low-purity hydrogen as well as pure hydrogen, package on-site cracking and storage with the fuel cell, and secure fuel supply agreements with ammonia and industrial gas producers. Offer fuel as a managed service with the system, and treat the fuel contract as the recurring revenue core of the business.
Lesson 4: The Buyer Is a Utility or Operator, and They Buy Resilience in Megawatts of Reliability
SRI's research identifies utilities as the largest end user, followed by industrial and commercial customers, and that defines the sale. Utilities, telecom operators and critical-infrastructure owners do not buy fuel cells on enthusiasm for hydrogen; they buy guaranteed availability, documented runtime, remote monitoring and a service agreement, procured through formal tenders against diesel and battery alternatives. The companies moving first have built their offers for that process: certified systems, availability guarantees, remote monitoring platforms, and the financing structures that let a capital-constrained operator pay for resilience as an operating expense.
Telecom is the proving ground. Mobile operators extending networks into off-grid regions in Asia Pacific, Africa and Latin America have thousands of sites running on diesel, and each is a candidate for a fuel cell with lower fuel logistics, lower maintenance and zero local emissions. SRI's research identifies Asia Pacific as both the largest and the fastest-growing region for this reason: the sites are there, the grid is unreliable and governments are supporting clean alternatives.
The same procurement logic applies to data centres and substations, where the alkaline cell competes for the backup role as diesel comes under emissions and permitting pressure.
Takeaway on go-to-market. Build the product for utility and operator procurement: certifications, availability guarantees, monitoring, service and financing. Use telecom tower electrification in Asia Pacific as the volume entry, reference it into substations and critical facilities, and structure offers as resilience-as-a-service where the customer pays for guaranteed power rather than for equipment.
Lesson 5: Policy Opens the Door, Economics Keeps It Open
Government support for hydrogen and clean energy, which SRI's research names as a driver, has created the demonstrations, grants and procurement preferences that gave alkaline fuel cells their second chance. But the same research names policy volatility as a restraint, and the hydrogen project cancellations recorded by the International Energy Agency in 2025 show what happens when projects depend on subsidy. The companies moving first have used policy support to reach commercial scale and then competed on economics: fuel cost per kilowatt-hour, maintenance per site-year and avoided diesel logistics.
That discipline also protects against the competing technologies SRI's research identifies. Solar and batteries will win where sun and short backup windows suffice; the alkaline fuel cell wins where runtime is measured in days, fuel can be stored for months and the site is far from service. Defining the product around that economic case, rather than around the policy case, is what makes the demand durable.
The capabilities that decide who captures this demand are specific:
Application focus on stationary, controlled-environment power where air sensitivity is managed and runtime matters.
Non-precious catalysts and durable membranes that sustain the cost advantage over the system's life.
Fuel flexibility across ammonia, by-product and pure hydrogen, packaged with supply and cracking.
Procurement-ready offers for utilities and operators with guarantees, monitoring, service and financing.
Economic cases that stand without subsidy against diesel, batteries and competing fuel cells.
Companies evaluating these competitive dynamics in greater detail can use SRI's Alkaline Fuel Cells Market analysis to assess type, application, end-user and regional segments and the positioning of the leading fuel cell developers.
Takeaway on policy and economics. Use grants, demonstrations and procurement preferences to reach scale, but build every commercial case on unsubsidised economics against the diesel and battery alternatives at the site. Track hydrogen and ammonia price trajectories and policy changes as risk variables, and position the product where runtime, storage and remoteness make the fuel cell the lowest-cost resilient option regardless of subsidy.
Where the Opportunity Is Concentrating
Value is moving toward stationary resilience, toward fuel flexibility and toward Asia Pacific.
By type, hydrogen-fed cells are the largest segment, anion exchange membrane designs are the technology bridge that improves air tolerance and manufacturability, and direct alcohol cells are expected to grow fastest in portable and small stationary applications where liquid fuel logistics are simplest.
By application, stationary power is the largest and most proven segment, transportation is a niche where the technology competes selectively, portable power serves defence and remote operations, and space and defence remain the heritage market with specialised demand.
By end user, utilities are the largest segment, industrial and commercial customers are growing on backup and off-grid demand, and residential remains small.
By geography, Asia Pacific is both the largest and the fastest-growing region on off-grid telecom, industrial demand and government support, Europe is advancing on hydrogen policy and demonstrations, and North America is growing on data centre and critical-infrastructure backup.
At the Horizon: What to Watch Over the Next Three Years
Field durability of platinum-free stacks. The transition of 2026 laboratory power densities into multi-year field data will determine whether the cost advantage holds and which developers can offer bankable guarantees.
Ammonia-to-power deployments. The number of ammonia-fed systems installed at telecom and off-grid sites, and their fuel cost per kilowatt-hour, will show whether fuel flexibility converts into volume.
Diesel restrictions at critical sites. Emissions and permitting rules for backup generators at data centres, substations and urban facilities will set the pace at which fuel cells displace diesel in the highest-value backup segment.
"The next phase of competition in alkaline fuel cells will not be won by the chemistry with the best headline. It will be won by the system a telecom operator trusts to keep a tower running for a week on fuel that arrived by truck."
The Strategic Revenue Opportunity
For fuel cell developers, the task is to focus on stationary resilience, protect the catalyst and membrane advantage, and package fuel supply with the system. For component and materials suppliers, the priority is durable membranes, non-precious catalysts and crackers. For utilities, telecom operators and critical-facility owners, the opportunity is to replace diesel at the sites where fuel cells already win on economics. For investors, the signal is the convergence of platinum-free performance, fuel flexibility and resilience procurement in a market growing from a small base.
Market intelligence turns these questions into decisions. Segment-level sizing shows where spend is concentrating across applications and regions, competitive benchmarking shows where alkaline developers stand against proton exchange membrane, solid oxide and battery alternatives, and regional analysis shows which markets will electrify off-grid and backup sites first. This is the path from market signals to strategic insight to revenue impact.
Takeaway on revenue. Treat the alkaline fuel cells market as four revenue pools with different buyers and sales cycles: stationary backup systems sold to utilities and operators on availability, off-grid power sold to telecom on fuel logistics and maintenance, fuel supply and cracking sold as a recurring service, and component and licensing revenue from catalysts and membranes. Each needs its own guarantee and channel. Enter where diesel is being regulated out and the grid cannot be trusted.
The Next Leg: Preparing for the Journey Ahead
The defining shift in alkaline fuel cells is that the technology's original weakness has become irrelevant in the applications that now matter, and its original strength, a cheap catalyst, has become decisive. That changes the buyer, the business case and the competitive map. The companies moving first are not the ones with the most laboratory records; they are the ones who chose stationary resilience, built durable platinum-free stacks, solved the fuel supply, learned to sell to utilities and operators, and built economics that stand without subsidy.
The next three years will decide which developers own the resilient power niche as hydrogen and ammonia supply mature. Decision-makers should focus the application, protect the cost advantage, sell the fuel with the cell, build for procurement and compete on economics.
