Zusammenfassung:The present invention relates to a fuel cell including a housing, at least one proton-conducting first ply, which is covered on both sides by catalyst plies, gas-permeable electrodes on the catalyst plies, and second plies in the form of electrically conductive plates arranged on the catalyst plies and on both sides of the first plies, which second plies are in electrically conductive contact with the electrodes in close proximity and delimit, together with the electrodes, gas-conducting channels, the first ply being in contact with the second ply with an essentially even surface. A fuel cell, comprising a housing, at least one first proton-conducting layer covered by catalyst layers on both sides, gas-permeable electrodes on the catalyst layers and second layers arranged on both sides of the first layers, whereby said second layers take the form of electro-conductive plates that are located in closely adjacent electro-conductive contact with the electrodes, define gas conducting channels in conjunction with the electrodes and one layer touches the other layer by means of a substantially planar surface. The electrodes are made of at least one layer of electro-conductive polymer fibers that is intersected by flow channels running parallel to the surface thereof in at least one direction.
