With the EFOY fuel cell you always have your environmentally friendly power generator with you – in your motor home, on the boat, or in your shed or cabin.
With the EFOY fuel cell you always have your own compact power generator with you and are completely independent off the power grid. The EFOY fully automatically recharges all common 12 or 24 V battery types reliably, quietly and in an environmentally friendly way. Whether in a motor home, on a boat or in a garden shed, or cabin, you decide where the EFOY will be used.

That ideal job for the EFOY fuel cell
No more sweating in the sun. The EFOY Fuel cell always produces power, unlike solar panels or wind generators, which means that even in bad weather, or during long periods of winter, you are always prepared. You can also combine solar with your EFOY Fuel cell for more options.
The EFOY produces quiet power and is as loud as a laptop’s fan. Noise pollution from noisy diesel generators is a thing of the past.
The EFOY recharges your battery fully automatically and requires no maintenance to do so. It switches on when the battery needs recharging and switches off again when the battery is full, you only have to change the fuel cartridge when it’s empty.
The EFOY generates environmentally friendly electricity. In a chemical process; only waste heat and water vapour with a small amount of CO2 are produced in addition to electricity. Therefore, the EFOY can be installed indoors without hesitation.
The fuel
EFOY fuel cells need our EFOY fuel cartridges to generate electricity. They contain high-purity methanol* and are a safety-tested system specially developed for EFOY fuel cells. The EFOY fuel cartridge can be changed in seconds.
EFOY Hybrid Power is a perfectly matched energy package consisting of EFOY fuel cells as power generators and EFOY lithium batteries as power storage. The smart Battery Management System (BMS) of the EFOY lithium battery ensures intelligent communication between the fuel cell and battery.
Our fuel cells are available in two power classes for different energy requirements.

Find the model that suits you
Determine your energy requirements with our model check and find the right combination of fuel cell and battery for your needs.
You can control the fuel cell easily with the EFOY app on your smartphone or tablet. All you have to do is plug the Bluetooth adapter into the EFOY. In the app you can see all the information about your fuel cell and battery at a glance. Example: monitor the fill level of your fuel cartridge or the daily consumption by simply downloading the EFOY app from the App Store.
There’s always a place for the EFOY. Due to its compact design it takes up little space and is also very light. We’ll show you where the EFOY can be installed in our installation area.
You can find the EFOY’s scope of delivery and optional accessories here.
Of course, our EFOY fuel cells also work with other power generators. In combination with solar modules, for example, they only turn on when the solar module cannot deliver sufficient power due to bad weather (e.g. snow, overcast skies, standing in the shade, etc.).
Whether in the harbor, at the buoy or in a lonely bay. The EFOY fuel cell supplies your boat’s electric motor with power, thus not only increasing its range but also ensuring a reliable on-board power supply. For all autonomous sailors and boaters the perfect solution to set sail in an environmentally friendly way. E-motors suitable for the EFOY can be found here: ePropulsion
The new generation of EFOY fuel cells has arrived. We will show you what we have improved and what’s new.
