    摘要： A membrane electrode assembly having a peripheral edge region and a central region. The membrane electrode assembly comprises an ion-conducting membrane, first and second electrocatalyst layers disposed either side of the ion-conducting membrane, and first and second gas diffusion layers disposed either side of the first and second electrocatalyst layers respectively. The membrane electrode assembly further comprises an edge protection member, the edge protection member comprising a film layer, a bonding layer, and one or more additives selected from the group consisting of free radical decomposition catalyst, self regenerating antioxidant, hydrogen donors (H-donor) primary antioxidant, free radical scavenger secondary antioxidant, oxygen absorbers (oxygen scavenger) and elemental palladium. The edge protection member is positioned between the membrane and the first and/or second gas diffusion layer at the peripheral edge region of the membrane electrode assembly, and the edge protection member overlaps the first and/or second electrocatalyst layers.
