Abstract: A method for operating a fuel cell system including a fuel feeder supplying fuel, a reformer producing a hydrogen-containing gas by a reforming reaction, a fuel cell which includes a cathode and an anode, a combustor which combusts an anode off-gas discharged from the anode to produce a combustion gas, a temperature detector detecting the temperature of the combustion gas, and a storage device storing a preset target temperature profile, the target temperature profile including the temporal change in target temperature of the combustion gas in the operation of the fuel cell system, includes controlling the flow rate of the fuel supplied from the fuel feeder to the reformer in the operation such that the temperature detected by the temperature detector becomes equal to a target temperature determined on the basis of the target temperature profile.

Abstract: The present invention provides a fuel cell system using combustion heat for an evaporator and a desulfurizer effectively. The fuel cell system comprises a combustor, a reformer, a fuel cell, a first cathode air heating part, a desulfurizer and an evaporator. A mixture of oxygen and gas which is contained in fuel is combusted in the combustor. A combustion exhaust gas generated in the combustor flows in the fuel cell system in such a manner that the combustion exhaust gas gives thermal energy to the reformer, the first cathode air heating part, the desulfurizer, and the evaporator in this order.
