Abstract

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.
