Title:
Electrolyte membrane * electrode zygote
Document Type and Number:
Japanese Patent JP5928013
Kind Code:
B2
Abstract:
An electrolyte membrane-electrode assembly comprises a polymer electrolyte membrane; a cathode catalyst layer and a cathode gas diffusion layer including a cathode micro porous layer and a cathode gas diffusion layer substrate, arranged in order on one side of the polymer electrolyte membrane, and an anode catalyst layer and an anode gas diffusion layer including an anode micro porous layer and an anode gas diffusion layer substrate, arranged in order on the other side of the polymer electrolyte membrane. A relative gas diffusion coefficient of the anode micro porous layer is smaller than a relative gas diffusion coefficient of the cathode micro porous layer by an amount equal to or greater than 0.05[-].
