The fuel offers significant advantages for mobile and portable applications because the liquid alcohol methanol can be transported anywhere safely, conveniently and effortlessly in the practical EFOY fuel cartridges.
According to the CLP Regulation, methanol is categorised as a poisonous and easily flammable substance. Please see the Safety Data Sheet for further details.
The EFOY fuel cell converts chemical energy into electrical energy without interim stages, without moving parts and without much loss of efficiency. That is why it is such an efficient power generator. The innovative and patented developments of the EFOY fuel cell enable a miniaturised set-up, high performance, a long service life and a low weight. Using the technology developed in-house, SFC has acquired a unique technological and competitive edge in the field of fuel cell systems for off-grid equipment with the EFOY fuel cells.
Of course, the 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 during bad weather.
The stack is the power-generating core of the EFOY fuel cells. It consists of individual cells, each of which is set up to include an anode, a cathode and a membrane. The membrane, as an electrolyte, separates anode from cathode. Positively charged, electric particles, so-called protons, can diffuse through the membrane. On the side of the anode, water and methanol are added, on the side of the cathode, oxygen is taken from the ambient air. In the reaction on 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. This makes the EFOY fuel cell very environmentally friendly.
