Abstract
A fuel cell system includes a compressor, a relief valve that adjusts a pressure of a cathode gas, a pulsation operation unit that pulsates an anode gas pressure, a target flow rate setting unit that sets a target flow rate of the cathode gas, a first target pressure setting unit that sets a first target pressure of the cathode gas, a second target pressure setting unit that sets a second target pressure of the cathode gas for maintaining a pressure difference between an anode and a cathode within a predetermined allowable range, a target pressure setting unit that sets the higher one of the first and second target pressures as a target pressure, and a control unit that controls the compressor on the basis of the target flow rate and a limitative pressure obtained by limiting pulsation of the target pressure.
