This fuel-cell system, which supplies an anode gas and a cathode gas to fuel cells and makes said fuel cells generate electricity in accordance with a load, has a supply passage via which the anode gas is supplied to the fuel cells and a pressure-regulating valve that is provided in said supply passage and regulates the pressure of the anode gas. This fuel-cell system also has a discharge passage via which the anode gas is discharged from the fuel cells and an ejector that uses the anode gas supplied from the pressure-regulating valve to draw in the anode gas discharged to the discharge passage and circulates said anode gas back to the fuel cells. This fuel-cell system further has a control unit that makes the pressure of the anode gas supplied to the ejector vary in a pulsing manner. |
