The EFOY fuel cell converts chemical energy into electrical energy without any interim stages, moving parts or much loss of efficiency. The underlying principle is an electrochemical process that is also known as "cold combustion". It is in principle the reversal of electrolysis. The EFOY fuel cells are based on DMFC (Direct Methanol Fuel Cell) technology. They generate power by using methanol provided in a fuel cartridge, in combination with oxygen from the air. Methanol is directly converted into power by the fuel cell. By products in the electromechanical process, include waste heat, water vapour and a small amount of carbon dioxide. Thus, a fuel cell is not an energy storage devise but an energy generating devise.
