A fuel cell system that includes a pressure regulating valve configured to control a pressure of an anode gas to be supplied to a fuel cell, a buffer unit configured to store an anode off-gas discharged from the fuel cell, and a purge valve configured to control an amount to be discharged to an outside of the anode off-gas stored in the buffer unit, and that periodically increases/decreases the pressure of the anode gas by periodically opening/closing the pressure regulating valve, controls the purge valve so that a purge flow rate increases more during pressure reduction of the pulsation operation than during pressure increase in pulsation operation control. |
