Abstract
The invention relates to a membrane-electrode assembly (100), comprising two electrodes (110, 110′) and a membrane (120), preferably a polymer electrolyte membrane (PEM), which is disposed between the two electrodes (110, 110′), wherein the membrane-electrode assembly (100) comprises a first cover layer (130; 130′) and a second cover layer (140; 140′) on at least one flat side, preferably on both flat sides of the membrane (120), characterized in that the first cover layer (130; 130′) covers an edge face (125, 125′) of the membrane (120) and an electrode edge face (115, 115′) facing the membrane (120) and the second cover layer (140; 140′) partially covers the first cover layer (130; 130′), preferably in edge regions of the membrane-electrode assembly (100). The present invention further relates to a fuel cell which comprises a membrane-electrode assembly (100).
