Abstract
The invention relates to a gas diffusion electrode for polymer electrolyte fuel cells having a working temperature of up to 250° C., comprising a plurality of gas-permeable electroconductive layers having at least one gas diffusion layer and one catalyst layer. The catalyst layer contains particles of an average particle diameter in the nanometer range, said particles containing ionogenic groups. The invention also relates to the production of said gas diffusion electrode and to the use of same in high-temperature polymer electrolyte membrane fuel cells.
