The bipolar plate is of a relatively simple design and a low production cost. In addition, it only requires two supply ducts. It consists essentially of a separator ( 20 ) sandwiched between two distributors ( 14 ) each consisting of a deformed sheet so that a distribution channel ( 16 A, 16 B) is formed on each of the two sides. A central hole ( 15 ) is used to connect both channels so as to only form a single distribution channel from one end of the distributor to the other. The fuel and oxidant gases may be evacuated to the outside or collected in peripheral evacuation holes ( 28 ) similar to the supply holes ( 17 ).
