Disclosed is a fuel cell wherein deterioration of fuel cell performance due to dry up phenomenon and flooding phenomenon is suppressed. Specifically disclosed is an assembly for fuel cells or a fuel cell wherein a catalyst layer contains a first composite catalyst particle containing a catalyst supporting particle and a solid polymer electrolyte and a second composite catalyst particle having a larger volume average particle diameter than the first composite catalyst particle and arrangement of the first composite catalyst particle and the second composite catalyst particle is controlled in the thickness direction of the catalyst layer. Consequently, deterioration of fuel cell performance due to dry up phenomenon or flooding phenomenon can be suppressed, thereby realizing a fuel cell with high efficiency.

L'invention concerne une pile à combustible protégée d'une dégradation des performances due à un assèchement ou un engorgement. L'invention concerne en particulier un ensemble pour une ou plusieurs piles à combustible, incorporant une couche de catalyseur contenant des premières particules de catalyseur composites composées de particules de support de catalyseur et d'un électrolyte polymère solide et des deuxièmes particules de catalyseur composites dont le diamètre moyen est supérieur à celui des premières particules de catalyseur composites. Les premières particules de catalyseur composites et les deuxièmes particules de catalyseur composites sont disposées d'une façon bien déterminée dans le sens de l'épaisseur de la couche de catalyseur. L'invention permet d'empêcher une dégradation des performances due à un assèchement ou un engorgement et donc d'obtenir une pile à combustible à haut rendement.
