摘要：The invention relates to a membrane electrode assembly which comprises twogas diffusion layers, each contacted with a catalyst layer, which are separated by apolymer-electrolyte membrane. Said polymer electrolyte membrane has an inner areawhich is contacted with a catalyst layer, and an outer area which is not provided on thesurface of a gas diffusion layer. The inventive assembly is characterized in that thethickness of all components of the outer area is 50 to 100 %, based on the thickness ofall components of the inner area. The thickness of the outer area decreases over a periodof 5 hours by not more than 5 % at a temperature of 80 °C and a pressure of 5 N/mm2.The decrease in thickness is determined after a first compression step which takes placeover a period of 1 minute at a pressure of 5 N/mm2.
