Abstract:
(EN) The present invention relates to a membrane-electrode assembly, a method for manufacturing the same, and a fuel cell comprising the same. The membrane-electrode assembly comprises: a catalyst layer; an interfacial adhesion layer disposed on the catalyst layer, an interface between the interface adhesion layer and the catalyst layer penetrating to some depth of the catalyst layer; and an ion exchange membrane disposed on the interfacial adhesion layer and binding with the catalyst layer via the interfacial adhesion layer, wherein the interfacial adhesion layer contains a fluorine-based ionomer having an equivalent weight (EW) of 500 g/eq to 1000 g/eq. In the membrane-electrode assembly, the problem of deterioration in hydrogen ion conductivity performance of the membrane-electrode assembly can be overcome through the improvement of the interfacial binding and interfacial stability between the electrode and the ion-exchange membrane; the hydrogen gas crossover can be reduced through the reduction in gas permeability without increasing interfacial resistance and interfacial binding problems; and the performance and durability under high temperature/low humidity conditions can be improved.
(FR) La présente invention se rapporte à un ensemble membrane-électrode, à son procédé de fabrication, et à une pile à combustible le comprenant. L'ensemble membrane-électrode comprend : une couche de catalyseur ; une couche d'adhésion interfaciale disposée sur la couche de catalyseur, une interface entre la couche d'adhésion d'interface et la couche de catalyseur pénétrant à une certaine profondeur de la couche de catalyseur ; et une membrane échangeuse d'ions disposée sur la couche d'adhésion interfaciale et se liant avec la couche de catalyseur par l'intermédiaire de la couche d'adhésion interfaciale, la couche d'adhésion interfaciale contenant un ionomère à base de fluor ayant un poids équivalent (EW) de 500 g/éq à 1000 g/éq. Dans l'ensemble membrane-électrode, le problème de détérioration de la performance de conductivité d'ions hydrogène de l'ensemble membrane-électrode peut être surmonté par l'amélioration de la liaison interfaciale et de la stabilité interfaciale entre l'électrode et la membrane échangeuse d'ions ; le croisement de gaz hydrogène peut être réduit par la réduction de la perméabilité au gaz sans augmenter la résistance interfaciale et les problèmes de liaison interfaciale ; et les performances ainsi que la durabilité dans des conditions de température élevée/faible humidité peuvent être améliorées.
(KO) 본 발명은 막-전극 어셈블리, 이의 제조 방법 그리고 이를 포함하는 연료 전지에 관한 것으로서, 상기 막-전극 어셈블리는 촉매층, 상기 촉매층 위에 위치하며, 상기 촉매층과의 계면이 상기 촉매층의 일부 깊이까지 스며든 계면 접착층, 그리고 상기 계면 접착층 위에 위치하며, 상기 계면 접착층을 매개로 상기 촉매층과 접합되는 이온 교환막을 포함하며, 상기 계면 접착층은 당량(equivalent weight, EW)이 500 g/eq 내지 1000 g/eq인 불소계 이오노머를 포함한다. 상기 막-전극 어셈블리는 전극과 이온 교환막 사이의 계면 접합성 및 계면 안정성이 개선되어 막-전극 어셈블리의 수소 이온 전도 성능 저하 문제를 극복할 수 있고, 계면 저항 증가 및 계면 접합 문제 없이 가스 투과도가 감소되어 수소 가스 크로스오버(crossover)가 저감되고, 고온/저가습 조건에서의 성능 및 내구성이 향상될 수 있다.
