Abstract
A fuel cell system includes a fuel cell in which a first reactant gas and a second reactant gas are supplied to generate electricity. An evaporator evaporates a raw fuel, which combustor exhaust gas discharged from the fuel cell and uses the exhaust gas to evaporate and volatile a raw material for the first reactant gas. A reformer reforms the evaporated and volatilized raw fuel vapor of the raw material by a reforming catalyst to produce the first reactant gas. An air-introducing device introduces the air that is used to be reformed into the evaporator or the reformed in a manner wherein the flow rate of the air is controlled depending upon the output from the fuel cell and upon the temperature of the raw fuel vapor.
