ABSTRACT:
In the fuel cell including a membrane electrode assembly, the diffusion layer of the membrane electrode assembly includes an electrode part having one surface in contact with the electrode catalytic layer and the other surface facing the separator and a non-electric-power generating part around the electrode part having one surface in contact with the solid polymer electrolytic membrane and the other surface facing the separator. The non-electric-power generating part includes a hydrophilic part near an outlet of the fluid passage of the reaction gas, and a hydrophobic layer formed on the hydrophilic part and exposed to the fluid passage to discharge water generated in generating an electric power.
