PROBLEM TO BE SOLVED: To quickly and stably start a fuel cell device by supplying heating liquid water to a fuel cell, when temperature is low, particularly even if it is below zero degree Centigrade. SOLUTION: This fuel cell device is provided with a water supply means for passing cooling water, in an oxygen pole passage of the fuel cell as a heat medium in a liquid condition and a circulation system for cooling water, including a water tank 40 recovering and storing cooling water. The water tank consists of a main tank 401 and a tank 402 for freezing, having smaller capacity than that of the main tank, and a heating means 47 is arranged in the tank for freezing. Since the fuel cell is heated in a liquid condition and heating of small capacity water or keeping it warm is sufficient, when the temperature is low, quick start can be realized. |
