ELECTROCHEMICAL CELL COMPRISING ELECTRICALLY CONDUCTIVE BIPOLAR PLATES OR END PLATES MADE OF POLYMER COMPOSITE MATERIAL

摘要

The invention relates to a fuel cell comprising a polymer electrolyte membrane and two gas diffusion electrodes, which are arranged on both sides of said membrane and which are terminated by electrically conductive end plates. The end plates are produced in an injection molding and are comprised of a thermoplastic base material (6) and of a non-metallic substance (7) that increases the conductivity, for example carbon. Metal fibers (8) are incorporated inside the base material in order to additionally increase the conductivity.
