Title (EN) MEMBRANE ELECTRODE ASSEMBLY AND SOLID POLYMER FUEL CELL
(FR) ENSEMBLE MEMBRANE-ÉLECTRODE ET PILE À COMBUSTIBLE À POLYMÈRE SOLIDE
Abstract:
(EN) A membrane electrode assembly is provided that includes a nanostructured thin film catalyst as the anode electrode catalyst, the membrane electrode assembly having robustness to humidity variation. Additionally, a solid polymer fuel cell including this membrane electrode assembly is provided. A membrane electrode assembly of an embodiment of the present disclosure includes an electrolyte membrane; an anode electrode catalyst layer in contact with the electrolyte membrane; an anode gas diffusion layer; and a fluorinated polymer layer in contact with the anode electrode catalyst layer between the anode electrode catalyst layer and the anode gas diffusion layer. The anode electrode catalyst layer includes a plurality of nanostructure elements including acicular microstructured support whiskers supporting nanoscopic catalyst particles; and the fluorinated polymer layer includes one of fully-fluorinated or partially-fluorinated polymer particles that have been dispersed in a network form.
(FR) L'invention concerne un ensemble membrane-électrode qui comprend un catalyseur à film mince nanostructuré en tant que catalyseur d'électrode d'anode, l'ensemble membrane-électrode ayant une robustesse face à la variation d'humidité. De plus, l'invention concerne une pile à combustible à polymère solide comprenant cet ensemble membrane-électrode. Un ensemble membrane-électrode selon un mode de réalisation de la présente invention comprend une membrane électrolytique; une couche de catalyseur d'électrode d'anode en contact avec la membrane électrolytique; une couche de diffusion de gaz d'anode; et une couche de polymère fluoré en contact avec la couche de catalyseur d'électrode d'anode entre la couche de catalyseur d'électrode d'anode et la couche de diffusion de gaz d'anode. La couche de catalyseur d'électrode d'anode comprend une pluralité d'éléments de nanostructure comprenant des trichites support microstructurées aciculaires portant des particules de catalyseur nanoscopiques; et la couche de polymère fluoré comprend des particules de polymère entièrement fluorés ou partiellement fluorés qui ont été dispersées sous une forme de réseau.
