Abstract

L'invention concerne une membrane électrolytique souple, conductrice de protons et imperméable aux éléments réactionnels d'une pile à combustible. Destinée à une pile à combustible, cette membrane est composée d'un support perméable, souple, ajouré et contenant des fibres polymères et une matière pouvant conduire des protons de manière sélective à travers la membrane. Cette invention concerne une membrane conductrice de protons, un procédé de fabrication associé et son utilisation. La membrane selon l'invention représente une nouvelle catégorie de membranes solides conductrices de protons, dont la base est un support souple et poreux contenant des fibres polymères, de préférence un non-tissé polymère. Ce support est d'abord infiltré d'une matière conductrice de protons, puis la membrane est séchée et la matière conductrice de protons se solidifie en un gel ou en une matière cristalline pour former une membrane conductrice de protons imperméable. La membrane électrolytique selon l'invention reste souple et peut être facilement utilisée dans une pile à combustible.
