Abstract

In manufacturing a membrane electrode assembly, an anode catalyst layer (130a) is formed on one side of an electrolyte membrane (110) and then a cathode catalyst layer (130c) is formed on the other side of the electrolyte membrane (110). Next, an anode gas diffusion layer (120a) is hot-press joined to the surface of the anode catalyst layer (130a) and a cathode gas diffusion layer (120c) is hot-press joined to the surface of the cathode catalyst layer (130c). The applied pressure during the hot-press joining at a region (120Rb), where the anode catalyst layer (130a) and the cathode catalyst layer (130c) are not formed on the electrolyte membrane (110), is less than the applied pressure at a region (120Ra), where the anode catalyst layer (130a) and the cathode catalyst layer (130c) are formed on the electrolyte membrane (110).
