Title (EN) GAS DIFFUSION ELECTRODE
(FR) ÉLECTRODE DE DIFFUSION GAZEUSE
(JA) ガス拡散電極
Abstract:
(EN) The present invention provides a fuel cell gas diffusion layer that achieves both good performance and durability. The present invention is a gas diffusion electrode having a microporous layer on at least one side of a conductive porous base material, the gas diffusion electrode being characterized in that the microporous layer has, at least, a first microporous layer in contact with the conductive porous base material, and a second microporous layer, the second microporous layer being the topmost layer of the microporous layer, and the second microporous layer containing a conductive material having linear portions.
(FR) La présente invention concerne une couche de diffusion gazeuse de pile à combustible qui permet d'obtenir à la fois de bonnes performances et une grande durabilité. Plus précisément, l'invention concerne une électrode de diffusion gazeuse possédant une couche microporeuse sur au moins un côté d'un matériau de base conducteur poreux, l'électrode de diffusion gazeuse étant caractérisée en ce que la couche microporeuse possède, au moins, une première couche microporeuse en contact avec le matériau de base conducteur poreux, et une seconde couche microporeuse, la seconde couche microporeuse étant la couche la plus supérieure de la couche microporeuse, et la seconde couche microporeuse contenant un matériau conducteur présentant des parties linéaires.
(JA) 本発明は、性能と耐久性を両立させた燃料電池ガス拡散層を提供する。本発明は、導電性多孔質基材の少なくとも片面に、微多孔層を有する、ガス拡散電極であって、前記微多孔層は、導電性多孔質基材に接する第1の微多孔層、及び第2の微多孔層を少なくとも有し、前記第2の微多孔層は、微多孔層の最表層にあり、前記第2の微多孔層が、線状部分を有する導電性材料を含むことを特徴とする、ガス拡散電極である。
