Abstract:
(EN) The present invention relates to a polymer electrolyte membrane, a method for manufacturing the same, and a membrane-electrode assembly comprising the same. The polymer electrolyte membrane comprises: a porous support body comprising multiple pores; a first layer comprising a first ion conductor that fills inner pores of one side surface of the porous support body; and a second layer comprising a second ion conductor that fills inner pores of the other side surface of the porous support body. The first ion conductor and the second ion conductor are different from each other. One selected from the group consisting of the first layer, the second layer, and a combination thereof comprises an organic antioxidant. The polymer electrolyte membrane has an excellent shape stability and has an improved resistance to radicals that occur during operations. Accordingly, the polymer electrolyte membrane has an excellent stability against radicals (that is, chemical stability), has an excellent ion conductivity performance, and can reduce the hydrogen transmittance.
(FR) La présente invention se rapporte à une membrane à électrolyte polymère, à son procédé de fabrication, et à un ensemble membrane-électrodes la comprenant. La membrane à électrolyte polymère comprend : un corps de support poreux comprenant de multiples pores ; une première couche comprenant un premier conducteur ionique qui remplit les pores internes d'une surface latérale du corps de support poreux ; et une seconde couche comprenant un second conducteur ionique qui remplit les pores internes de l'autre surface latérale du corps de support poreux. Le premier conducteur ionique et le second conducteur ionique sont différents l'un de l'autre. Un élément choisi dans le groupe constitué de la première couche, de la seconde couche et d'une combinaison des deux comprend un antioxydant organique. La membrane à électrolyte polymère présente une excellente stabilité de forme et présente une résistance améliorée aux radicaux qui apparaissent pendant le fonctionnement. Par conséquent, la membrane à électrolyte polymère présente une excellente stabilité vis-à-vis des radicaux (c'est-à-dire la stabilité chimique), présente d'excellentes performances de conductivité ionique, et peut réduire la perméabilité à l'hydrogène.
(KO) 본 발명은 고분자 전해질 막, 이의 제조 방법 및 이를 포함하는 막-전극 어셈블리에 관한 것으로서, 상기 고분자 전해질 막은 다수의 공극(pore)을 포함하는 다공성 지지체, 상기 다공성 지지체의 한 쪽면의 내부 공극을 채우고 있는 제 1 이온 전도체를 포함하는 제 1 층, 및 상기 다공성 지지체의 다른 한 쪽면의 내부 공극을 채우고 있는 제 2 이온 전도체를 포함하는 제 2 층을 포함하며, 상기 제 1 이온 전도체와 상기 제 2 이온 전도체는 서로 상이하고, 상기 제 1 층, 상기 제 2 층 및 이들의 조합으로 이루어진 군에서 선택되는 어느 하나는 유기계 산화 방지제를 포함한다. 상기 고분자 전해질 막은 형태 안정성이 우수하면서도, 운전 중 발생하는 라디칼에 대한 내성이 향상되어 라디칼에 대한 안정성, 즉 화학적인 안정성이 우수하고, 이온 전도도 성능이 우수하면서도 수소 투과도를 저감시킬 수 있다.
