Abstract

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.
