A fuel cell system is provided with a regulator which controls the anode gas fed to a fuel cell, a buffer section that stocks the anode off gas discharged from the fuel cell, and a purge valve which controls the volume of anode off gas stored in the buffer section discharged to the exterior. By cyclically opening and closing the regulator, the pressure of the anode gas is increased and reduced cyclically. In pulsating operating control, during depressurization of pulsating operation, the purge value is controlled in such a manner that the purge flowrate is increased relative to when pressure is increased. |
