Hydrogen fuel cell forklift system, 15 kW.
A complete 15 kW fuel cell power system with a matched 35 MPa hydrogen supply kit — refuels in minutes through a standard TN1 nozzle, runs full multi-shift duty, and emits only water. Complete 3.5 t forklift truck also available.
Why a Fuel Cell Forklift
Minutes to Refuel, Not Hours to Charge
The TN1 fueling port connects to any standard hydrogen station nozzle — refuel like diesel, with no battery swap rooms or spare battery inventory.
Full Power Until the Tank Is Empty
A forklift fuel cell system delivers constant voltage — lifting speed never fades as the shift goes on, unlike batteries.
Zero Emissions, Indoor & Cold-Storage Ready
The only exhaust is water vapor, and the system starts reliably at -20 °C — safe for enclosed warehouses, cold chain and food-grade sites.
Compact, Integrated & Safe
A 200 kg integrated power module with layered safety: TPRD thermal relief, excess-flow shutoff and dual pressure monitoring on every cylinder.

System Architecture — Four Integrated Modules
Hydrogenation Module
The TN1 fueling port is designed to GB/T 26779-2011 with an integrated filter and check valve, and connects directly to the nozzle of any standard hydrogen refueling station.
Pressure Reduction Module
A 100 NLPM pressure reducing valve with safety relief valve (110 ± 10 kPa) and low-pressure sensor delivers a stable 60 kPa supply to the stack under all load conditions.
Hydrogen Storage Module
The 53 L aluminum-lined composite cylinder carries a bottle valve with glass-bulb TPRD, high-pressure solenoid and stop valves — and combined temperature + pressure sensing lets the system calculate remaining hydrogen.
Safety & Piping
An excess-flow valve automatically closes the bottle valve if a high-pressure line is damaged. High-pressure sections use 3/8 in thick-wall piping, with emergency exhaust routed out of the vehicle.

Where Hydrogen Forklift Trucks Pay Off
Fuel Cell vs Battery Forklift
| Fuel Cell Forklift | Battery Forklift | |
|---|---|---|
| Refuel / recharge | Minutes at a standard hydrogen nozzle | 4–8 hours of charging |
| Power through the shift | Constant voltage, full lifting speed to empty | Performance fades as the battery drains |
| Multi-shift operation | Refuel and continue — no downtime | Spare batteries and swap rooms required |
| Cold storage | Rated to -20 °C | Capacity and charge acceptance drop in the cold |
| Indoor emissions | Water vapor only | Zero at point of use |
| Fleet infrastructure | One compact fueling point | Charging rooms, chargers, spare battery inventory |
Need the refueling side too? HydroXcel also builds electric hydrogen compressors and air-driven gas boosters for on-site cylinder filling and forklift refueling — one supplier for the complete setup.
Frequently Asked Questions
How is the system refueled?
Through the standard TN1 fueling port, which connects directly to hydrogen station nozzles — a 35 MPa fill takes minutes, not the 4–8 hours a battery forklift needs to charge.
Fuel cell vs battery forklift — which should I choose?
Single-shift, low-utilization sites do fine with batteries. If you run multiple shifts, high utilization, or a large fleet at one location, a fuel cell forklift pays back through eliminated downtime and a smaller fleet.
How much does a hydrogen fuel cell forklift cost?
It depends on your fleet size, duty cycle and whether you also need the hydrogen supply side. The economics improve fast with utilization: multi-shift fleets save on spare batteries, swap rooms and downtime. Tell us your operation and we will quote a system — and a payback estimate — for your case.
Who manufactures this fuel cell forklift system?
HydroXcel designs and builds the complete system in-house. The forklift system is built on our 20–60 kW liquid-cooled stack platform — -30 °C cold start, 3.25 kW/L power density, 15,000-hour design life — already proven in forklift and passenger vehicle applications.
Can it operate indoors and in cold storage?
Yes. Zero local emissions make it safe for enclosed spaces, and the system is rated for -20 °C operation — better cold performance than lead-acid or lithium batteries.
Can the system be adapted to my forklift model?
Tell us your truck brand, voltage platform and duty cycle — our engineers will confirm fit and configure the power and hydrogen supply side. For general selection guidance, see Choosing the Right Hydrogen Fuel Cell.
Do you sell the complete forklift truck?
Yes — the HX-FL-20K is a complete 3.5 t fuel cell forklift truck with a 20 kW fuel cell engine and 53 L @ 35 MPa Type IV hydrogen storage, ready for turnkey fleet deployment.
How do I supply hydrogen for a forklift fleet?
We supply the refueling side as well: electric hydrogen compressors and air-driven boosters for on-site cylinder filling. For sites that also need backup or prime power, see our 5–20 kW generator line.
