CA 2253076

A gas diffusion layer comprising an electro-conductive porous material and 16-55% by weight of fluororesin added thereto is used for at least one of the positive electrode and the negative electrode, whereby the water-retaining property of the inside of the membrane/electrodes assembly is improved without hindering gas diffusion to enable the polymer electrolyte to be moistened with water formed at the positive electrode, and resultantly a polymer electrolyte fuel cell which operates by unhumidified gas is provided.

Une couche de diffusion gazeuse renfermant un matériau poreux électroconducteur et 16-55 % en poids de fluororésine ajoutée est utilisée pour au moins l'une des deux électrodes, soit l'électrode positive et l'électrode négative; par ce processus, la propriété de rétention de l'eau de l'intérieur du dispositif membrane/électrodes est amélioré sans gêner la diffusion gazeuse, de façon à permettre l'humidification de l'électrolyte polymérique avec l'eau formée à l'électrode positive; on obtient ainsi finalement une cellule à combustible électrolytique polymérique, fonctionnant avec du gaz non humidifié.
