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 (16A, 16B) 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).
