A fuel cell system, which supplies anode gas and cathode gas to a fuel cell for power generation, comprises: a control valve that controls the pressure of the anode gas supplied to the fuel cell; pulsation operating means which controls the degree of opening of the control valve based on the operating state of the fuel cell system so as to pulsate the pressure of the anode gas in the fuel cell using a predetermined pressure; and a stagnation point determining means which determines whether a stagnation point, at which the concentration of the anode gas is locally lower in the fuel cell, is present or not based on a change in the pressure of the anode gas in the fuel cell. When a stagnation point is determined to be present in the fuel cell, the pulsation operating means performs a pulsation operation by increasing the predetermined pressure. |
