Why fuel cells aren’t widely used (yet)

They aren’t mainstream because hydrogen remains expensive and hard to deliver, fuel-cell stacks still cost too much and degrade faster than buyers expect, and the overall energy efficiency lags batteries—while public refueling infrastructure is sparse and unreliable in most markets. Put simply: the technology works, but economics, durability, and infrastructure have not caught up to make fuel cells practical for mass deployment across most use cases.

The core technical and economic hurdles

Fuel cells can convert hydrogen into electricity cleanly at the point of use, but a chain of constraints—cost, durability, fuel supply, and efficiency—limits adoption, especially in passenger transport. The following are the most cited barriers engineers, fleets, and policymakers face today.

• High cost of stacks and systems: Proton-exchange membrane (PEM) stacks still rely on expensive materials (notably platinum-group catalysts) and precision manufacturing. Low production volumes keep per-kilowatt costs high, and full systems add compressors, humidifiers, cooling, and power electronics.
• Durability and reliability gaps: PEM stacks are sensitive to start-stop cycles, impurities, and freeze/thaw conditions. Many real-world systems struggle to deliver automotive-grade lifetimes without expensive maintenance, while heavy-duty targets (30,000–50,000+ operating hours) remain challenging across varied duty cycles.
• Hydrogen supply and price: Most hydrogen made today is “grey” from natural gas, which is carbon-intensive. “Green” hydrogen via electrolysis is growing but remains costly in many regions. Retail hydrogen for cars in the U.S. has often been around $25–$36 per kilogram, translating to steep per-mile costs versus electricity or even gasoline.
• Infrastructure scarcity and reliability: Public refueling networks are thin outside a handful of regions (parts of California, Germany, Japan, South Korea). Station outages and supply interruptions have been frequent in some markets, undermining consumer confidence.
• Energy efficiency disadvantage vs. batteries: Using renewable electricity to make hydrogen, compress or liquefy it, transport it, and reconvert it in a fuel cell typically yields 25–40% overall end-to-end efficiency—well below the ~70–90% path for battery-electric charging and use.
• Storage and logistics hurdles: Hydrogen’s low volumetric energy density demands high-pressure (often 700 bar) or cryogenic storage, adding cost and complexity. Pipelines and materials must handle embrittlement risks, and liquefaction consumes substantial energy.
• Standardization and safety practice: While codes and standards exist and hydrogen can be managed safely, deployment requires specialized training, permitting, and facility adaptations that add time and cost.

These constraints compound: high-cost hydrogen plus expensive stacks and sparse stations create a feedback loop that suppresses demand and scale, keeping prices high and networks thin.

Infrastructure is the bottleneck

Even when vehicles or stationary systems are available, insufficient fueling capacity hampers adoption. Retail networks for light-duty vehicles number only in the hundreds globally, with clusters in a few countries. In the U.S., the California network has seen station closures and supply disruptions; Europe and Japan maintain broader coverage but still far from the ubiquity of gasoline or fast-charging. For heavy-duty fleets, dedicated private stations are emerging, but rollout pace and capital intensity remain significant constraints.

Storage and transport challenges

Delivering hydrogen at scale is nontrivial. Compressed gas requires frequent deliveries or on-site production; liquefied hydrogen reduces volume but adds a heavy energy penalty and boil-off losses; carriers like ammonia or liquid organic hydrogen carriers introduce conversion steps and purification needs before fueling sensitive PEM stacks. Each pathway affects delivered cost, carbon intensity, and reliability.

Where fuel cells do succeed today

Despite headwinds, fuel cells have carved out niches where their fast refueling, steady power, or high uptime outweigh disadvantages. These deployments inform where the technology can be most competitive near term.

• Material-handling fleets: Fuel-cell forklifts operate indoors with quick refueling, avoiding battery swap downtime. Large warehouse networks (e.g., big-box retailers) use thousands of units, supported by on-site hydrogen.
• Backup and prime power: Telecom towers, data centers, hospitals, and remote sites use fuel cells for clean backup power or continuous combined heat and power. Solid oxide fuel cells (SOFCs) offer high electrical efficiency for stationary use, though they run hot and ramp slowly.
• Buses and early heavy-duty trucks: City buses and pilot freight corridors in Europe, North America, and Asia show practical operations, especially where depot fueling is centralized. Costs remain higher than diesel or many battery options, but duty cycles with long range and high utilization can fit fuel cells.
• Rail and maritime pilots: Regional trains on non-electrified lines and demonstration vessels use hydrogen where overhead electrification or large batteries are impractical, though many rail agencies still prefer wire electrification when feasible.
• Specialized mobility and aerospace: From ground support equipment to long-endurance drones and space applications, fuel cells offer high specific energy and clean operation.

These niches work because they minimize exposure to public fueling networks, centralize hydrogen logistics, and monetize advantages like rapid refueling and continuous power.

How the picture could change

Analysts highlight several shifts that could make fuel cells more common in select sectors, even if batteries dominate much of road transport.

1. Cheaper, cleaner hydrogen: Scaling low-carbon hydrogen—via low-cost renewable power, high-capacity-factor electrolysis, or fossil pathways with verified low methane leakage and effective carbon capture—must push delivered prices toward the low single digits per kilogram while cutting lifecycle emissions.
2. Scaling manufacturing and cutting precious metals: High-volume stack production, lower platinum loadings, durable non-platinum catalysts, and simplified balance-of-plant can bring system costs down to automotive targets.
3. Durability breakthroughs: Robust membranes, catalysts, and water/thermal management that tolerate impurities, frequent cycling, and cold starts are key to multi-year warranties for heavy-duty fleets.
4. Reliable, right-sized stations: Standardized, modular stations with higher uptime and lower capital cost can stabilize user experience and TCO; for trucks, depot or corridor fueling can concentrate demand.
5. Policy clarity and carbon pricing: Predictable incentives and standards—such as clean hydrogen tax credits, emissions accounting rules, and procurement programs—can de-risk investment while rewarding genuinely low-carbon hydrogen.
6. Targeted applications: Focus on use cases where batteries are at a disadvantage (very high daily energy demand, minimal dwell time, weight-sensitive long range, or combined heat and power) can build sustainable early markets.

If these advances materialize together, fuel cells could expand in heavy transport, industrial power, and specific off-grid roles—even as batteries remain the default for most cars and many trucks.

Context and recent developments

Market signals since 2023 underscore the dichotomy. Battery-electric vehicles have surged, aided by maturing fast-charging networks and falling battery costs. Meanwhile, several hydrogen refueling networks in the U.S. have struggled with reliability and economics, and retail prices have remained high. In Europe and Asia, public investment continues, but expansion is measured. On the supply side, green hydrogen projects are advancing, helped by tax credits (such as the U.S. 45V incentive) and national strategies in the EU, Japan, and South Korea; however, stringent rules to ensure low-carbon electricity sourcing and time matching are shaping which projects pencil out. In heavy-duty trucking, early fuel-cell models and pilot corridors are operating, but fleet scale-up will hinge on dependable, affordable hydrogen and durable stacks.

Bottom line

Fuel cells aren’t widely used because the math doesn’t work for most users today: hydrogen fuel is costly and hard to find, stacks are pricey and don’t yet last long enough across all duty cycles, and the energy-efficiency penalty versus batteries is significant. Where logistics can be centralized and uptime is paramount—warehouses, buses, backup power, some heavy-duty routes—fuel cells already provide value. Wider adoption depends on cheaper clean hydrogen, more durable and lower-cost stacks, and reliable infrastructure targeted at the right applications.

Summary

Fuel cells face a convergence of challenges—high costs, limited fueling infrastructure, durability concerns, and an efficiency gap versus batteries—that limit mainstream use. They are gaining traction in niches that exploit fast refueling and continuous power, while broad passenger-vehicle adoption remains unlikely without major cost and infrastructure breakthroughs. Policy support and technology advances could expand their role in heavy transport and stationary power, but near-term electrification will continue to be led by batteries where they are simpler and cheaper to deploy.

Why use a fuel cell instead of a gas tank?

Fuel cells offer other features that make it safer in the event of a crash: Higher burst strength than a fuel tank. Non-Vented Cap and Tip-Over Valve to prevent spilling in a rollover. Many fuel cells also have a bladder and/or Fuel Cell Foam as additional safety precautions.

Is a fuel cell bad for the environment?

Fuel cells have lower or zero emissions compared to combustion engines. Hydrogen fuel cells emit only water, addressing critical climate challenges as there are no carbon dioxide emissions. There also are no air pollutants that create smog and cause health problems at the point of operation.
