摘要： The invention relates to a membrane-electrode unit comprising two gas diffusion layers, each layer being in contact with a catalyst layer and said gas diffusion layers being separated by a polymer electrolyte membrane. A polymer frame is provided on at least one of the two surfaces of the polymer electrolyte membrane that are in contact with the catalyst layer. Said polymer frame comprises an inner region that lies on at least one surface of the polymer electrolyte membrane and an outer region that lies outside the gas diffusion layer.
