Engineered for the Road
-30°C Cold Start
Cold-start unit brings the stack online in freezing conditions — the 80 kW engine starts at -30°C in 123 seconds, rated for -30°C to 60°C operation.
IP67 Sealed
Commercial-duty engines are IP67 water- and dust-tight, vibration-tested to SAE J2380 — rain, snow, wash-downs and rough roads included.
12,000+ Hour Life
Graphite-plate stacks rated beyond 12,000 hours of service — years of fleet duty, not a pilot-project experiment.
System, Not Just a Stack
Hydrogen supply, air, thermal management, FCU control and boost PCU integrated at the factory — one interface to your vehicle.
The Engines
HX-400W-AV — Two-Wheeler System
A 5.4 kg air-cooled module sized for standard 25 km/h e-bike platforms — highly integrated, fast-starting, nearly maintenance-free.
In the field: e-scooter fleets run 80–100 km per fill, refueled on-site with HydroXcel compressors.
HX-3.5K-WV — Light Vehicle System
Water-cooled graphite stack with a simplified air path — no complex cooling or proportional valves, cutting cost for light fleets. -30°C cold start, IP55.
In the field: sightseeing and patrol cars cover 130 km per fill in scenic areas, campuses and parks.
HX-5K-WV — Cart & Utility System
The golf-cart power unit: modular block design for multi-unit parallel operation, one-button start/stop, and an intelligent display of temperature, pressure and current.
In the field: 11-seat golf carts running all-day duty in resort fleets.
HX-15K-WV — Forklift System
Purpose-built for warehouse duty with a matched 53L @ 35MPa onboard hydrogen supply system — full-shift power with 3-minute refills.
In the field: warehouse forklifts run full shifts on this system, refueling in 3 minutes.
HX-30K-WV — Passenger & Light Truck Engine
For pickups, engineering vehicles and light/medium platforms — 140-cell graphite stack in a compact 138.5 kg package, customizable to different power levels.
Case: Cold-Chain Refrigerated Truck
A 4.8-ton refrigerated truck on HydroXcel fuel cell power — the cold chain stays cold all day, the route stays emission-free, and refueling takes minutes instead of charging hours.
HX-65K-WV — Commercial Vehicle Engine
The fleet-proven workhorse for buses, sanitation and logistics trucks — IP67 sealed, -30°C cold start, running today in city bus service.
On the Road: 65 kW City Bus
A Golden Dragon city bus running our HX-65K-WV engine — daily route service with a full tank of hydrogen and zero tailpipe emissions.
HX-80K-WV — Heavy-Duty Engine
Flagship engine for heavy trucks and coaches: 85 kW peak, 61.3% maximum system efficiency, 450–750 V high-voltage output, fully standards-compliant (GB/T 33978, GB 24549).
Frequently Asked Questions
Can you retrofit my existing vehicles?
Yes — our engines are complete, boundary-defined systems (stack, hydrogen, air, thermal, control, PCU). Send us your vehicle platform, voltage architecture and duty cycle; our engineers return an integration proposal with mechanical and electrical interfaces.
Can power levels be customized?
Yes. Between the standard models we configure stacks and balance-of-plant to your required output — from light utility vehicles to heavy trucks. Custom voltage windows and dimensions are routine OEM work for us.
What about hydrogen storage and refueling?
We supply the whole chain: onboard hydrogen storage, compressors and boosters, and refueling interfaces — one engineering team for the vehicle and the fuel.
Do you sell complete vehicles?
For light platforms, yes — scooters, sightseeing cars, golf carts and forklifts are available as complete vehicles on our hydrogen vehicles page. For buses and trucks we supply the engine system to vehicle manufacturers and fleet integrators.
What hydrogen purity do the engines need?
Standard fuel-cell grade: ≥99.99% with CO below 1 PPM (per GB/T 37244 / ISO 14687). Any commercial hydrogen source meeting this spec works with our engines.
