Provided is a membrane-electrode assembly having both improved performance and durability. One embodiment of the present invention provides a membrane-electrode assembly comprising: a polymer electrolyte membrane; a first catalyst layer disposed on at least one surface of the polymer electrolyte membrane; and a second catalyst layer disposed on the polymer electrolyte membrane, wherein the first catalyst layer is interposed between the polymer electrolyte membrane and the second catalyst layer, and the first catalyst layer includes platelet mesoporous carbon. L'invention concerne un ensemble membrane-électrodes ayant à la fois des performances et une durabilité améliorées. Un mode de réalisation de la présente invention concerne un ensemble membrane-électrodes comprenant : une membrane électrolytique polymère ; une première couche de catalyseur disposée sur au moins une surface de la membrane électrolytique polymère ; et une seconde couche de catalyseur disposée sur la membrane électrolytique polymère, la première couche de catalyseur étant interposée entre la membrane électrolytique polymère et la seconde couche de catalyseur, et la première couche de catalyseur comprenant du carbone mésoporeux plaquettaire. 내구성과 성능을 동시에 개선하는 막-전극 어셈블리가 제공된다. 본 발명의 일 실시예는 고분자 전해질막 및 상기 고분자 전해질막의 적어도 일면 상에 배치된 제1 촉매층 및 상기 고분자 전해질막 상에 배치된 제2 촉매층을 포함하고 상기 제1 촉매층은, 상기 고분자 전해질막 및 상기 제2 촉매층 사이에 개재되고, 상기 제1 촉매층은, 판상의 메조다공성 탄소(platelet mesoporous carbon)를 포함하는 막-전극 어셈블리를 제공한다.
