1. A fuel cell comprising:

  • a housing;

    at least one proton-conducting first ply having sides, and which is covered by catalyst plies on both of its sides;

    gas-permeable electrodes on the catalyst plies;

    second plies in the form of electrically conductive plates arranged on both sides of the first plies, which contact the electrodes in an electrically conductive manner and delimit, together with the electrodes, gas-conducting channels, at least one if the first and second plies having an essentially planar surface, and the electrodes being formed, through at least one layer, by electrically conductive fibers having a titer of 10 to 50 dtex made of a polymeric material, which are traversed in at least one direction by flow channels running parallel to their surfaces, wherein the layer has a multi-ply structure and includes at least one open-structured support ply between two covering plies with the covering plies having a higher density than the open-structured support ply.
