A fuel cell system for generating electricity by feeding an anode gas and a cathode gas to a fuel cell comprises a buffer tank for storing an anode offgas discharged from the fuel cell, a control valve for controlling the pressure of the anode gas supplied to the fuel cell, and an anode gas pressure control means for controlling the control valve and increasing the anode gas pressure in response to greater demanded output. The anode gas pressure control means adjusts the degree of opening of the control valve to a predetermined degree of opening during transient operation in which the demanded output has lessened. |
