POWER SUPPLY PLATE FOR A COPLANAR CIRCUIT FUEL CELL

摘要

The invention relates to a bipolar reduced-thickness plate comprising channels (21) for simultaneously circulating a fuel, combustible and a coolant (41) in the same plane. The inventive power supply plate, preferably made of a composite material, is provided on each side thereof (1A, 1B) with a circuit network for circulating a fuel or combustible which are supplied by supply holes (2, 3) passing through the plate. Cooling is carried out by means of supply holes (4) which feed one or several cooling channels (41) embodied between the parts of fuel or combustible channels (21). Through passages (43) enable the channels to pass from one surface to the other in such a way as to provide the circulation and removal of the coolant. Said invention also makes it possible to distribute a fuel and combustible on both sides of the plate and to simultaneously carry out the cooling process. The invention can be used for high-power and medium-power fuel cells.
