Abstract: A microporous layer sheet for a fuel cell according to the present invention includes at least two microporous layers, which are stacked on a gas diffusion layer substrate, and contain a carbon material and a binder. Then, the microporous layer sheet for a fuel cell is characterized in that a content of the binder in the microporous layer as a first layer located on the gas diffusion layer substrate side is smaller than contents of the binder in the microporous layers other than the first layer. The microporous layer sheet for a fuel cell, which is as described above, can ensure gas permeability and drainage performance without lowering strength. Hence, the microporous layer sheet for a fuel cell, which is as described above, can contribute to performance enhancement of a polymer electrolyte fuel cell by application thereof to a gas diffusion layer.
