The invention relates to a fuel cell comprising components such as current diverters, solid polymer electrolytes in the form of diaphragms, gas distribution rings and power distributors as components, whereby all components are manufactured from a parent thermoplastic polymer dissolved in a solvent and that the parent polymer is modified for each of the components such that the current diverters (1) are electrically conductive, the diaphragms (4) are ion-conductive, the current distributors (3) are permeable to gas and electrically conductive and the gas distribution rings (2) are made of non-modifyable and/or electrically conductive parent polymer and that the components are joined without seals by means of a composite process.
