Abstract[English]
A catalyst-coated membrane for a water electrolyser is provided. The catalyst-coated membrane comprises a polymer electrolyte membrane with an anode catalyst layer on a first side of the membrane. The anode catalyst layer comprises an oxygen evolution reaction catalyst containing at least one noble metal at a loading of the oxygen evolution reaction catalyst, based on the noble metal content, of less than or equal to 0.6 mg/cm2. The polymer electrolyte membrane comprises a membrane layer comprising dispersed platinum group metal-containing nanoparticles, a nanoparticle stabilising agent and an ion-conducting polymer.[French]
L'invention concerne une membrane revêtue de catalyseur pour un électrolyseur d'eau. La membrane revêtue de catalyseur comprend une membrane électrolytique polymère pourvue d'une couche de catalyseur d'anode sur un premier côté de la membrane. La couche de catalyseur d'anode comporte un catalyseur de réaction de dégagement d'oxygène contenant au moins un métal noble à une charge du catalyseur de réaction de dégagement d'oxygène, sur la base de la teneur en métal noble, inférieure ou égale à 0,6 mg/cm2. La membrane électrolytique polymère comprend une couche de membrane comportant des nanoparticules dispersées contenant un métal du groupe du platine, un agent stabilisant les nanoparticules et un polymère conducteur d'ions.
