Membrane electrode assembly, and fuel cell, electrolytic cell, electrochemical hydrogen compressor, redox flow battery or electrochemical sensor comprising the membrane electrode assembly

Abstract

A membrane electrode assembly includes a cathode, an anode, a proton-conductive membrane arranged between the cathode and the anode and a sealing frame which surrounds the cathode, the anode and the membrane at the edges thereof, wherein in the inner region of the sealing frame at least mutually superposed subregions of the cathode, of the anode and of the membrane are exposed, wherein the sealing frame in the layer thickness direction comprises a first sealing layer and a second sealing layer which are bonded to each other by an adhesive and wherein the first sealing layer and/or the second sealing layer has a reinforcement structure.
