EFOY Comfort 80 Fuel Cell

EFOY Fuel Cells: Where power is always available

Now you can have power wherever and whenever you want; there’s no need to compromise safety or convenience. If you’ve got a EFOY fuel cell you will always have a source of electrical power but without the noise and the odor. The EFOY fuel cell is Lightweight and compact (7 kg) and measures 443mm x 202mm x 288mm. The EFOY fuel cell works cleanly and economically using methanol cartridges (available above) and producing a constant 12V supply. The only thing it puts out besides electrical power is water and carbon dioxide in an amount comparable to a child’s breath. The built-in Automatic Charge Control regulator constantly monitors voltage and recharges the battery completely automatically. If voltage dips below 12.3 volts, the EFOY fuel cell will cut in automatically to recharge the battery. It then shuts itself off – again, fully automatically. Once you switch it on, that’s it the EFOY fuel cell will communicate with you via the display on the remote control (standard supplied equipment). And it usually does that every couple of weeks when the fuel cartridge needs changing. Changing cartridges is also a matter of a few seconds, even if the EFOY fuel cell is running. 

Ideal applications for the EFOY fuel cell: Ideal applications for the EFOY fuel cell include mobile homes, camper vans, boats / yacht's, holiday homes and holiday cabins or any application where you need temporary power.

Light weight and compact: Every centimeter and every gram counts. The EFOY fuel cell weighs a mere 7 kg and measures 44.3 x 20.2 x 28.8. Lightweight and compact, it will fit into any boat, car, mobile home and caravan. And the practical EFOY fuel cartridge mean that you can now take several weeks of power with you and if you run out there are sources all over the world for the methanol. On-board marine and land power has never been easier.

Extremely quiet

EFOY fuel cells work so quietly that they won’t disturb you even if you’re sleeping. If you install it in the bilge of your boat or back of your RV, it will be practically inaudible. That’s a big advantage over normal generators! You’ll always have a fully-charged battery no matter how remote you are, plus you’ll have your peace and quiet, too.

Comparison to a solar panel

How does the EFOY fuel cell work in comparison to regular generators?

An EFOY fuel cell converts liquid methanol directly into electrical energy. A noiseless chemical process transforms methanol and oxygen directly into electrical current without any combustion. The use of ultra-pure, high-quality materials plus precision components make the EFOY fuel cell possible. A mixture of methanol and water is introduced on the anode side of the membrane. The needed water comes from the internal, patented, fully automatic water return system within the unit. The unit pumps ambient air into the fuel cell on the cathode side. The anode and cathode sides are joined by an electrical circuit. The methanol releases electrons (e-) to the anode when it comes into contact with the catalytic converter. These electrons then flow over the circuit in the direction of the cathode. Protons (H+) are likewise released passing through the membrane to flow to the cathode. There, oxygen reacts with protons and electrons to form water. The entire reaction takes place at the heart of the fuel cell, called the stack. The stack heats up to about 75°C during the chemical reaction. Thus, any water not needed in the process is released as evaporation into the atmosphere. A very small amount of carbon dioxide also arises; as much as what is found in a small child’s breath. This unique chemical process enables the cell to transform the medium directly into electricity. There are no intermediate steps and no loss of energy. Since the stack contains no mechanical components whatsoever, energy generation proceeds extremely quietly.
