To obtain a fuel cell system which has a hydrogen fuel supplying system and is good in the response to the requirement of output increase.
In the hydrogen fuel supplying system 12 of the fuel cell system 10, a hydrocarbon raw material and steam are supplied to a first reactor 18A, a reforming process is performed, and a hydrogen-containing fuel gas formed in the reforming process is supplied to a fuel cell 14 and consumed in the cell in a first state of a switching device 20. An anode offgas discharged from an anode offgas outlet 14B of the fuel cell is introduced into a second reactor 18B as a gas for regeneration. In the second reactor 18B, temperature raising/heat storing for performing the reforming process, that is to say, a regeneration process is performed. By switching to the second state of the switching device 20, the state is changed to such a state that the regeneration process is performed in the first reactor and the reforming process is performed in the second reactor. When the power generation amount of the fuel cell is increased, a valve V12 is opened and the anode offgas is introduced, as operation gas, to the reactor 18 in which the reforming process is performed.
