EFOY fuel cells need our EFOY fuel cartridges to generate electricity. These contain high-purity methanol and have a safety-tested system specifically developed for EFOY fuel cells. With just one movement, the EFOY fuel cartridge can be changed in seconds.. With an M10 fuel cartridge, you can travel for up to 4 weeks without the need for a power outlet and enjoy your freedom.
According to the CLP Regulation, methanol is categorised as a poisonous and easily flammable substance. For further information, please see the Safety Data Sheets in our downloads.
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 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.
