PURPOSE:To provide effective and new methods for the humidifying method of the fuel hydrogen on a hydrogen electrode side for wetting an electrolyte film and the discharging method of water on an air electrode (or oxygen electrode) side. CONSTITUTION:In a fuel cell arranged with a solid polymer electrode film 2, a gas separator constituting element 1B kept in contact with a hydrogen electrode (anode) side is made of a conductive, water-repellent, porous body or a conductive, hydrophilic, porous body. A gas separator constituting element 1A kept in contact with an air electrode or an oxygen electrode (cathode) side is made of a conductive solid body, a cooling water passage 6 is formed in a gas separator 1, the water transportation characteristic (capillary action) of the porous body is utilized to feed water to the hydrogen electrode, and water is discharged from the air electrode. |
