The present invention relates to a membrane-electrode assembly comprising a fluorine-containing catalyst layer, and a fuel cell comprising same. The membrane-electrode assembly of the present invention comprises a fluorine-containing catalyst layer, and thus exhibits high hydrophobicity through a fluorine-doped or fluorine-containing nano-coating, thereby enabling the implementation of excellent water-repellent properties. Accordingly, water management in an electrode may be improved, and the durability and performance of the membrane-electrode assembly may be enhanced. La présente invention concerne un assemblage membrane-électrodes comprenant une couche de catalyseur contenant du fluor, et une pile à combustible le comprenant. L'assemblage membrane-électrodes de la présente invention comprend une couche de catalyseur contenant du fluor, et présente ainsi une hydrophobicité élevée du fait d'un nano-revêtement dopé au fluor ou contenant du fluor, ce qui permet la mise en oeuvre d'excellentes propriétés hydrofuges. Par conséquent, la gestion de l'eau dans une électrode peut être améliorée, et la durabilité et les performances de l'assemblage membrane-électrodes peuvent être améliorées. 본 발명은 불소 함유 촉매층을 포함하는 막-전극 어셈블리 및 이를 포함하는 연료 전지에 관한 것이다. 본 발명의 막-전극 어셈블리는 불소 함유 촉매층을 포함함으로써 불소 도핑 또는 불소 함유 나노 코팅을 통하여 높은 소수성이 발휘되어 우수한 발수 특성 구현이 가능하다. 이에 따라 전극내 물 관리의 개선이 가능해지며, 막-전극 어셈블리의 내구성과 성능이 향상된다.
