Designed for use in marine environments with an extremely long lifetime, this 400 W fuel cell based generator will endure harsh conditions. Easy to use and with a smart and compact design, the generator produces DC power to run the GPS, radio, bilge pump, lights and more.

UP400 is virtually silent when operating. It requires minimal annual maintenance and refueling is quick and easy. The fuel cell works in parallel with a battery module, which is used during start-up and shut-down. The fuel cell acts as the main power source during operation.

The unit requires hydrogen gas, which is provided by external cylinders, and adequate ventilation for oxygen supply. It is environmentally friendly and can be used in sensitive areas, including inside yachts, motorhomes and off-grid homes.

Golden rule for UP400 is that 1 litre of hydrogen (in water volume at 300 bars) will last for 1 hour at 400 W. If you would use 200 W, 1 litre of hydrogen would be enough for 2 hours. Thus, a 9 litre hydrogen cylinder would be enough to run 18 hours consecutively at 200 W.

Solar panel Solar panel


Our novel solution allows you to connect the fuel cell unit in combination with an external battery with solar panels and wind turbines to produce and store excessive energy for future usage. The UP400 integrates fuel cells with pioneering battery technologies to make the generator smart. Form your own miniature smart-grid and go energy independent.


The generator delivers power on-demand, no matter the weather condition or temperature. The UP400 fuel cell can act as a battery charger or stand-alone power source.

Stormy ocean


You will never need to open the unit. No more time and energy wasted on maintenance! The compact design and light weight of the UP400 fuel cell unit maximizes practicality and makes the generator easily portable.

No Pollution

UP400 delivers an immediate injection of power without the noise or smell of diesel generators. The only by-products of the generator are heat and water vapor.
