A fuel cell includes: a fuel supplying portion for supplying a fuel which is reformed at a temperature below 450.degree. C.; a gas generating portion for reforming the supplied fuel to generate a hydrogen containing gas; a temperature control portion for rapidly raising the temperature of the reformed hydrogen containing gas from 450.degree. C. to 600.degree. C. to supply the hydrogen containing gas while maintaining the temperature thereof; and a power generating portion for allowing the temperature controlled fuel to react with a separately supplied oxidizer to generate electricity. The power generating portion comprises at least a fuel electrode, to which the fuel temperature-controlled by the temperature control portion is supplied, and an oxidizer electrode, which is provided so as to face the fuel electrode via an electrolyte layer 6.
