Abstract[English]
A membrane-electrode assembly for a water electrolyser is provided. The membrane- electrode assembly comprises a polymer electrolyte membrane with a first face and a second face; an anode catalyst layer on the first face of the membrane, the anode catalyst layer comprising an oxygen evolution reaction catalyst; and a porous web of polymer fibres in contact with the anode catalyst layer, the polymer fibres comprising a conductive metal additive.[French]
L'invention concerne un assemblage électrode-membrane-électrode pour un électrolyseur d'eau. L'assemblage électrode-membrane-électrode comprend une membrane électrolytique polymère ayant une première face et une seconde face ; une couche de catalyseur d'anode sur la première face de la membrane, la couche de catalyseur d'anode comprenant un catalyseur de réaction de dégagement d'oxygène ; et une bande poreuse de fibres polymères en contact avec la couche de catalyseur d'anode, les fibres polymères comprenant un additif métallique conducteur.
