Title (EN) NANOWIRE-BASED MEMBRANE ELECTRODE ASSEMBLIES FOR FUEL CELLS
(FR) ELECTRODE MEMBRANAIRE A BASE DE NANOFILS POUR PILES A COMBUSTIBLE
Abstract:
(EN) The present invention disclosed nanowires (316) for use in a fuel cell comprising a metal catalyst deposited on a surface of the nanowires. A membrane electrode assembly for a fuel cell is disclosed which generally comprises a proton exchange membrane (306), an anode electrode (308) and a cathode electrode (310), wherein at least one or more of the anode electrode and cathode electrode comprise an interconnected network of the catalyst supported nanowires. Methods are also disclosed for preparing a membrane electrode assembly and fuel cell based upon an interconnected network of nanowires.
(FR) L'invention porte: sur des nanofils s'utilisant dans des piles à combustible, et dont la surface est revêtue d'un catalyseur métallique, et sur une électrode membranaire pour pile à combustible comportant d'une manière générale: une membrane échangeuse de protons, et électrode anodique et une électrode cathodique entre lesquelles se trouve un réseau de nanofils revêtus d'un catalyseur métallique interconnectés. L'invention porte également sur des procédés de préparation de ladite électrode membranaire et sur une pile à combustible utilisant un tel réseau de nanofils interconnectés.
