PROBLEM TO BE SOLVED: To provide a membrane electrode assembly including a gas diffusion layer that can balance water repellency, water holding property and conductivity well with a thickness thinner than conventional, and can enhance power generation performance furthermore, and to provide a fuel cell and a manufacturing method therefor.SOLUTION: An anode gas diffusion layer and a cathode gas diffusion layer are composed, respectively, of a porous member containing conductive particles and a polymer resin as main components. The porous member is a porous film formed by laminating more than one sheet having different porosity. |
