Abstract[English]
diffusion, a catalyst layer (14) adjacent to the gas diffusion layer (12) and comprising a copper-based cathode catalyst, and a conductive layer (16) adjacent to the catalyst layer (14), wherein the gas diffusion layer (12), the catalyst layer (14), and the conductive layer (16) together form a gas diffusion electrode, and wherein the catalyst layer (14) comprises a predefined amount of anion exchange ionomer (18) and the conductive layer (16) comprises at least one layer comprising a predefined amount of cation exchange ionomer (24). According to the invention, the conductive layer (16) comprises a graphite layer (20) comprising a predefined portion of the cation exchange ionomer (24).[French]
, une couche de catalyseur (14) adjacente à la couche de diffusion de gaz (12) et comprenant un catalyseur de cathode à base de cuivre, et une couche conductrice (16) adjacente à la couche de catalyseur (14), la couche de diffusion de gaz (12), la couche de catalyseur (14) et la couche conductrice (16) formant ensemble une électrode de diffusion de gaz, et la couche de catalyseur (14) comprenant une quantité prédéfinie d'ionomère échangeur d'anions (18) et la couche conductrice (16) comprenant au moins une couche comprenant une quantité prédéfinie d'ionomère échangeur de cations (24). Selon l'invention, la couche conductrice (16) comprend une couche de graphite (20) comprenant une partie prédéfinie de l'ionomère échangeur de cations (24).
