    • 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.
    • 的燃料电池(1)具有中心聚合物膜(2),聚合物膜(2)在两侧上覆盖Diffuserschichten(3,4),其Diffuserschichten(3,4)的后表面支撑表面的电极(5,6)具有开口(15,16) 盖和后盖(7,8)中,用气体连接(9,10),用于将平面电极中的至少一个(5,6)。 这里,之间的平面电极的至少一种(5,6)和相关联的盖(7,8)的至少两个相互平行并相互密封的气体导向通道(11,12; 13,14),其中,在表面电极的开口(15) (6)从在相邻的扩散层(4)和扩散片(4)到所述其它气体引导通道引线(14)的气体导管(13),并且其中,所述燃料电池(1)中的气体导向通道(11,13)的主延伸方向 一个更大的总长度大于具有垂直于此。
