METHOD FOR PRODUCING A FUEL CELL AND A FUEL CELL SYSTEM

摘要

A method is provided for producing a fuel cell, which method includes the arrangement of in each case one gas diffusion layer with in each case one bipolar plate on a respective side of a membrane electrode arrangement which comprises an anode, a cathode and an electrolyte membrane arranged between the anode and the cathode. The gas diffusion layers are set back in relation to the bipolar plates and the membrane electrode arrangement. The gas diffusion layers have in each case at least one reaction fluid supply region and in each case at least one reaction fluid discharge region and in each case at least one reaction fluid sealing region. The method is characterized by injecting a sealing material into at least one reaction fluid sealing region of at least one gas diffusion layer such that the gas diffusion layer is sealed off to the outside.
