PROBLEM TO BE SOLVED: To provide a fuel cell device having a new structure in which humidity of the electrolyte membrane can be maintained. SOLUTION: In the fuel cell device which has a fuel electrode and an air electrode, vapor form water is supplied to the air electrode. As the water supplied to the surface of the air electrode deprives preferentially the latent heat of the air, vaporization of the water from the electrolyte membrane of the air electrode side is prevented. Thereby, the electrolyte membrane is not dried at the air electrode side and can always keep a uniform humidity. |
