Abstract

A catalyst layer for a fuel cell membrane electrode assembly includes a plurality of agglomerates, adjacent ones of the plurality of agglomerates contacting with each other with pores provided between said adjacent ones of the plurality of agglomerates, each of the plurality of agglomerates being formed by packing a plurality of catalysts each consisting of noble metal fine particles supported on a fiber-like support material, adjacent ones of the plurality of catalysts contacting with each other with pores provided between said adjacent ones of the plurality of catalysts, and each of the plurality of catalysts contacting with a plurality of catalysts other than said each catalyst at a plurality of contact points. This allows providing a catalyst layer, a fuel cell membrane electrode assembly, and a fuel cell, each of which has compact size and excellent power generation performance, and a method for producing the same.
