A fuel cell (1) is provided with a central polymer membrane (2) that is provided with diffusion layers (3, 4) covering both sides and having plane electrodes (5, 6) supporting the back surface of said layers. The electrodes (5, 6) are provided with openings (15, 16) and rear covers (7, 8) with gas supplies (9, 10) for at least one of the plane electrodes (5, 6). At least two parallel extending gas flow channels (11, 12; 13, 14) sealed against each other are configured between at least one plane electrode (5, 6) and the cover (7, 8) pertaining thereto. Openings (15) in the plane electrode (6) extend from one gas flow channel (13) into the adjacent diffusion layer (4) and from the diffusion layer (4) into the other gas flow channel (14). The fuel cell (1) is provided with a greater dimension lengthwise in the main extension direction of the gas flow channels (11, 13) than vertical thereto. |
