(KO) 막-전극 접합체, 그 제조방법 및 이를 포함하는 연료전지
Abstract:
(EN) The present invention relates to a membrane-electrode assembly and a manufacturing method therefor and, more specifically, to: a membrane-electrode assembly wherein a cathode catalyst layer has a greater porosity at the position corresponding to an oxygen discharge part, than at the position corresponding to an oxygen feed part into which oxygen is fed, so as to facilitate the discharge of reaction products produced by an electrochemical reaction in a fuel cell; a method for manufacturing the same; and a fuel cell including the same.
(FR) La présente invention concerne un ensemble membrane-électrode et un procédé de fabrication de celui-ci et concerne plus spécifiquement : un ensemble membrane-électrode dans lequel une couche de catalyseur de cathode possède, au niveau de la position correspondant à une partie de décharge d'oxygène, une porosité supérieure à celle de la position correspondant à une partie d'alimentation en oxygène dans laquelle de l'oxygène est alimenté, de manière à faciliter la décharge de produits de réaction produits par une réaction électrochimique dans une pile à combustible ; un procédé de fabrication de cet ensemble ; ainsi qu'une pile à combustible comprenant celui-ci.
(KO) 본 발명은 막-전극 접합체 및 그 제조방법에 관한 것으로써, 좀 더 상세하게는, 산소가 투입되는 산소 투입부와 대응되는 위치의 양극 촉매층의 기공율 보다 산소 배출부와 대응되는 위치의 양극 촉매층의 기공율이 큼으로써, 연료전지의 전기화학적 반응에 의해 생성되는 반응물의 배출이 원활한 막-전극 접합체, 그 제조방법 및 이를 포함하는 연료전지에 관한 것이다.
