Abstract
A composite porous body, a gas diffusion layer member of a polymer electrolyte fuel cell, a cell member for the polymer electrolyte fuel cell, and manufacturing methods thereof are provided. The composite porous body is a metallic composite porous body in which a sheet-like metal portion composed of a composite porous body having a three-dimensional mesh structure and a resin portion extending in an in-plane direction of the metal portion are integrally formed with each other. The gas diffusion layer member of a polymer electrolyte fuel cell is composed of a composite porous body in which a sheet-like metal portion composed of a composite porous body having a three-dimensional mesh structure and a resin portion extending in an in-plane direction of the metal portion are integrally formed with each other. Also, the gas diffusion layer member of a polymer electrolyte fuel cell has a separator plate, and the conductive porous body placed on at least one surface of the separator plate. A resin frame is integrally provided so as to cover the peripheries of separator plate and the conductive porous body.
