EFOY
With the EFOY fuel cell you always have your environmentally friendly power generator with you – in your motorhome, on the boat, or in your shed or cabin.

EFOY Benefits
Your freedom. Your power.
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.
Lots of power in a small space.
Weighing only about 6 kg (13.2 lbs) and 27.5 cm high, the EFOY is a space miracle. Thanks to its compact design, the EFOY can be installed anywhere to save space.
Power in all weathers
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.
Enjoy the quiet!
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.
Completely worry-free!
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.
For the sake of the environment
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..

How it works
Environmentally friendly power generator
The EFOY fuel cell is the ideal power generator for your 12 V and 24 V battery. The integrated charge controller permanently monitors the charge level of your superstructure/on-board battery and recharges it fully automatically if necessary. It switches off again (standby mode) as soon as the battery is fully charged. This means that you always have full energy reserves and it protects your battery from damaging deep discharge through continuous charging. To operate 230 V consumers, such as coffee machines or hair dryers, you will also need an inverter.
The EFOY power generation principle
EFOY fuel cells are based on DMFC (Direct Methanol Fuel Cell) technology. They convert chemical energy into electrical energy without interim stages and without much loss of efficiency. The methanol in the fuel cartridge is supplemented by oxygen from the air, and is used to produce electricity. In addition to power, all this creates is waste heat and water vapour with little carbon dioxide, making it efficient and exceptionally environmentally friendly.
The principle of water recovery
The stack is the power-generating core of the EFOY fuel cell. It consists of individual cells, each of which is set up to include a cathode and a membrane. As an electrolyte, the membrane separates the anode and cathode from each other. Positively charged electrical particles, known as protons, can diffuse through the membrane. On the side of the anode, water and methanol are added, and on the side of the cathode, oxygen is taken from the ambient air. In the reaction at the anode, H+ ions and free electrons are created, as well as the reaction product carbon dioxide (CO2). The protons can cross the membrane. The electrons, however, have to travel to the cathode side via a connected electric circuit during which they generate power. On the cathode, the H+ ions, the oxygen from the air and the electrons are converted into water vapour
Installation
Thanks to its lightweight and compact design, there’s always room for the EFOY. We’ll show you where the EFOY fits and who can help you install it.
Maximum energy in the smallest space
The EFOY is lightweight and compact – it fits into the smallest of spaces. Ideal installation locations in the motorhome could be places like the rear garage, the side compartment or under the seat bench. On the boat you can install them in the locker or in the stern, however the EFOY can also be easily stored under the seat or in side compartments of the interior.
Your authorised EFOY dealer will be happy to help you find the right place.
