Abstract

La présente invention concerne un procédé de fabrication d'électrode à diffusion gazeuse, dans lequel les ions hydrogène produits dans une couche catalytique d'anode peuvent être efficacement conduits vers une membrane électrolyte en adoptant une couche de diffusion gazeuse et/ou une couche catalytique, comprenant un matériau polymère conducteur d'ions (un ionomère) couvrant de manière essentiellement régulière la paroi intérieure des pores (pores primaires) à l'intérieur des agrégats primaires de carbone sur lesquels un catalyseur métallique est supporté. En outre, des ions hydrogène peuvent efficacement arriver à une couche catalytique decathode, il est possible de supprimer une diminution de la vitesse de diffusion de matériaux d'oxygène et d'eau en tant que réactif et produit dans la cathode, et d'améliorer le taux d'utilisation du catalyseur métallique.
