Abstract[English]
A membrane-electrode assembly for a water electrolyser is provided. The membrane-electrode assembly comprises a polymer electrolyte membrane with a first major surface and a second major surface, and an anode component in contact with the first major surface of the polymer electrolyte membrane. The anode component comprises (i) a porous framework of polymer fibres at least partially coated with a metal-containing thin film; and (ii) an oxygen evolution reaction (OER) catalyst supported on the porous framework of polymer fibres.[French]
L'invention concerne un assemblage membrane-électrodes pour un électrolyseur d'eau. L'assemblage membrane-électrodes comprend une membrane électrolytique polymère ayant une première surface principale et une seconde surface principale, et un composant anodique en contact avec la première surface principale de la membrane électrolytique polymère. Le composant anodique comprend (i) une structure poreuse de fibres polymères revêtues au moins partiellement d'un film mince contenant du métal ; et (ii) un catalyseur de réaction de dégagement de l'oxygène (OER) supporté sur la structure poreuse de fibres polymères.
