PORTABLE POWER SERIES
Portable fuel cell generators,
from 250W to 3kW.
Silent, zero-emission power you can carry — from 7.9 kg, with native 24V / 48V DC output and an optional inverter for standard AC loads.
Why a Portable Fuel Cell Generator
Silent & Zero-Emission
No combustion, no exhaust after-treatment, no noise complaints. A portable fuel cell generator runs cleanly next to people, equipment and in emission-restricted zones where a diesel genset is not welcome.
Grab-and-Go Power
From 7.9 kg upward, these are genuine carry-on power units. Connect a standard hydrogen cylinder, press start, and be producing power in minutes — at a tower site, a field camp or an emergency scene.
DC-Native, AC-Ready
Native 24V / 48V DC connects directly to battery banks, DC buses and telecom power systems. Add a suitably sized inverter and standard AC loads run too.
No Coolant, No Fuss
Built on our air-cooled stack platform: no pump, no radiator, no coolant loop. Fewer parts means higher reliability and maintenance that takes minutes, not hours.

The Models
250 W
250W Portable Fuel Cell Generator — 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.
1 kW
1kW Portable Fuel Cell Generator — HX-1K-AG
Purpose-built for backup duty: a 45-cell metal-plate stack in a slim chassis that slides into equipment racks, shelters and home utility corners.
1.5 kW
1.5kW Portable Fuel Cell Generator — HX-1.5K-AG
Fifty percent more power in the same proven enclosure — a common fit for backup loads that outgrow a 1kW unit.
2 kW
2kW Portable Fuel Cell Generator — 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.
3 kW
3kW Portable Fuel Cell Generator — HX-3K-AG
The flagship: native 48V DC, titanium-alloy stack, CANbus monitoring and a built-in 1.5 kWh LFP battery that bridges load spikes and cylinder swaps.
Where It Works
Portable Fuel Cell vs Battery vs Diesel
| Portable Fuel Cell | Battery Pack | Diesel Genset | |
|---|---|---|---|
| Emissions | Zero at point of use | Zero at point of use | PM, NOx, CO₂ exhaust |
| Noise | Near-silent | Silent | Loud |
| Runtime | Extends by adding or swapping cylinders | Fixed by battery capacity | Extends with fuel tank size |
| Recharge / refuel | Swap or refill hydrogen supply | Hours of recharging | Refuel with diesel |
| Maintenance | No coolant loop, minimal parts | Minimal | Oil, filters, engine service |

Frequently Asked Questions
Can a portable fuel cell generator power a home?
Yes for the loads that matter most in an outage — a refrigerator, lighting, internet and communications, or small medical devices — through a suitably sized inverter. It is sized for essential circuits, not whole-house supply. For larger continuous power, see our 5–20kW water-cooled generators.
How long does it run on one cylinder?
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.
Is it safe to run near people?
Yes. There is no combustion and the exhaust is zero-emission — no PM, NOx, SOx, CO or CO₂ — and operation is near-silent. As with any hydrogen device, follow basic ventilation and handling guidelines.
Do I get AC power from these units?
They output 24V or 48V DC natively; pair any model with a suitably sized DC/AC inverter for standard AC loads. For built-in AC output and higher power, the water-cooled generator line outputs 230V / 380V AC directly.
What hydrogen supply do I 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.
Can it replace my diesel generator?
For loads up to 3kW where silence, zero emissions or indoor-adjacent operation matter — yes, and with far less maintenance. For higher power or long continuous runs, step up to the water-cooled line.
