Abstract:
A fuel cell system comprising:a fuel cell in which a first reactant gas and second reactant gas are supplied to generate electricity, an evaporator for evaporating a raw fuel, which combustor exhaust gas discharged from said fuel cell and makes use of said exhaust gas to evaporate and volatile a raw material as a raw fuel vapor for the first reactant gas, a reformer which reforms the evaporated and volatilized raw fuel vapor by means of a reforming catalyst to produce the first reactant gas, and an air-introducing device, which introduces air used to be reformed into said evaporator or said reformer, and which possesses a device for setting a flow rate of the air and a device for correcting the flow rate of the air so that the flow rate of the air is controlled, during a stationary state after the fuel cell has completed warming up, depending upon an output from the fuel cell and upon a temperature of the raw fuel vapor.
