Hydrogen power you can carry,
from 250W to 3kW.
Stable 24V / 48V DC output from 7.9 kg up — no coolant, no pumps, just hydrogen in and clean power out.

All models: PEM fuel cell, air-cooled stack, hydrogen purity ≥99.99% (CO<1ppm), ambient temperature 0–40°C, humidity 10–95%. Zero-emission exhaust — no PM, NOx, SOx, CO or CO₂.
Why Air Cooled
Simplicity Itself
Air cooling removes the pump, radiator and coolant loop entirely. Fewer parts means higher reliability, faster startup and maintenance that takes minutes, not hours.
Truly Portable
From 7.9 kg upward, these are genuine portable hydrogen generators — carry them to a tower site, a field camp or an emergency scene and be producing power in minutes.
Silent & Zero-Emission
No combustion, no exhaust after-treatment, no noise complaints. Safe to run near people, equipment and in emission-restricted zones.
Hybrid-Ready DC Output
Native 24V / 48V DC connects directly to battery banks, DC buses and telecom power systems. Add an inverter for standard AC loads.
The Models
HX-250W-AG
The lightest way to put hydrogen to work — ships with a regulator for standard 1.6 MPa cylinders: connect, open the valve, press start.
HX-1K-AG
Purpose-built for backup: a 45-cell metal-plate stack in a slim chassis that slides into equipment racks and shelters.
HX-1.5K-AG
Fifty percent more power in the same proven enclosure — a common fit for outdoor cabinets that outgrow a 1kW unit.
HX-2K-AG
Two kilowatts in a 25 kg package one person can still move — for field loads where a battery bank alone runs out too soon.
HX-3K-AG
The telecom-grade flagship: native 48V DC, titanium-alloy stack, CANbus monitoring and a built-in 1.5 kWh LFP battery.
Where They Work
Frequently Asked Questions
Air cooled vs water cooled fuel cells — which do I need?
Air-cooled systems trade a bit of efficiency for dramatic simplicity: no coolant loop, no pump, lighter weight, faster start. Below 3kW they are almost always the right choice. Above 5kW, water cooling sustains higher power density and longer continuous runs — see our 5–20kW water-cooled generators.
What hydrogen supply do these systems need?
All models run on low-pressure hydrogen at 0.6–0.7 bar with purity ≥99.99%. The 250W model includes a regulator for standard 1.6 MPa cylinders; larger models pair with our cylinder bundles or solid state storage for longer autonomy.
How long will a cylinder last?
As a rule of thumb, a 40L @ 15MPa cylinder holds roughly 6,000L of hydrogen — about 5 hours for the 1kW model at full load, or over 2 hours for the 3kW. Tell us your autonomy target and we will size the storage for you.
Can I get AC power from these DC systems?
Yes — pair any model with a suitably sized DC/AC inverter. For built-in AC output and higher power, the water-cooled generator line outputs 230V / 380V AC directly.
Do you build custom or vehicle versions?
Yes. Our vehicle line covers fuel cell systems from 400W to 80kW for two-wheelers, carts, buses and trucks — visit vehicle fuel cell engines or complete hydrogen vehicles.
