ABSTRACT:
A membrane electrode assembly that includes a cathode electrode catalyst layer and an anode electrode catalyst layer respectively disposed on one side and the other side of a solid polymer electrolyte membrane, gas diffusion layers disposed respectively on the sides of the electrode catalyst layers; and intermediate layers having pores and disposed respectively between the electrode catalyst layer and the gas diffusion layer and between the electrode catalyst layer and the gas diffusion layer. The volume per unit area and per unit mass of the pores having pore size of 0.1 to 10 μm in the intermediate layer in the cathode side is larger than that in the intermediate layer in the anode side. The pore volume of the intermediate layer in the cathode side is 1.7 to 4.3 μl/cm2/mg and that of the intermediate layer in the anode side is 0.5 to 1.4 μl/cm2/mg.
