The invention relates to a fuel cell with a current collector, polymeric solid electrolyte in the form of membranes, gas distributor rings and currents distributor as components, all components being made from a thermoplastic basic polymer soluble in a solvent, and in that this basic polymer is so modified for the individual components that the current collectors (1) are electrically conductive, the membranes (4) are ion-conductive, the current distributors (3) are gas-permeable and electrically conductive, and the gas distributor rings (2) are made of unmodified and/or electrically conductive basic polymer, and in that the components are combined by a bonding process without seals.
