A fuel cell system configured to generate power by supplying anode gas and cathode gas to a fuel cell includes a control valve for controlling a pressure of the anode gas to be supplied to the fuel cell, a buffer unit configured to store anode off-gas to be discharged from the fuel cell, a purge valve configured to adjust a flow rate of the anode off-gas discharged from the buffer unit, a pulsating operation unit configured to increase and vary the pressure of the anode gas downstream of the control valve according to a load of the fuel cell, and a purge unit configured to control an opening of the purge valve according to the load of the fuel cell. The purge unit increases the opening of the purge valve controlled according to the load of the fuel cell during a down transient operation in which the load of the fuel cell decreases. |
