Abstract
(EN)
Disclosed is a membrane-electrode assembly provided with an anode (5B), a cathode (5A), a polymer electrolyte membrane (1), and either a first carbon layer (2A) disposed between either an anode catalyst layer (3B) and/or a cathode catalyst layer (3A) and the polymer electrolyte membrane (1) and/or a second carbon layer (2B) disposed either between the anode catalyst layer (3B) and an anode gas diffusion layer (4B) and/or between the cathode catalyst layer (3A) and a cathode gas diffusion layer (4A), wherein the carbon layer is configured such that the ionization tendency of carbon in the carbon layer is larger than the ionization tendency of catalyst-supported carbon in either the anode catalyst layer (3B) and/or the cathode catalyst layer (3A) and the amount of supported catalyst in the carbon layer is smaller than the amount of supported catalyst in either the anode catalyst layer (3B) and/or the cathode catalyst layer (3A).

L'invention porte sur un ensemble membrane-électrode comprenant une anode (5B), une cathode (5A), une membrane électrolytique polymère (1), et une première couche de carbone (2A) agencée entre une couche de catalyseur d'anode (3B) et/ou une couche de catalyseur de cathode (3A) et la membrane électrolytique polymère (1) et/ou une seconde couche de carbone (2B) agencée entre la couche de catalyseur d'anode (3B) et une couche de diffusion de gaz d'anode (4B) et/ou entre la couche de catalyseur de cathode (3A) et une couche de diffusion de gaz de cathode (4A). La couche de carbone est configurée de telle manière que la tendance à l'ionisation du carbone contenu dans la couche de carbone est plus grande que la tendance à l'ionisation du carbone supporté par le catalyseur dans la couche de catalyseur d'anode (3B) et/ou la couche de catalyseur de cathode (3A), et la quantité de catalyseur supporté dans la couche de carbone est inférieure à la quantité de catalyseur supporté dans la couche de catalyseur d'anode (3B) et/ou la couche de catalyseur de cathode.
