Abstract
A fuel cell system supplies anode and cathode gases, and generates power through an electrochemical reaction of the gases in accordance with a load. The system includes a compressor that supplies the cathode gas to a fuel cell stack, and a pressure regulator valve that adjusts the pressure of the cathode gas in the fuel cell stack. The system sets a target cathode pressure based on a power generation request to the fuel cell stack, and controls an operation amount of the compressor and an opening degree of a pressure regulator valve based on the target cathode pressure. The temperature of air discharged by the compressor is restricted to an upper temperature limit by restricting the operation amount of the compressor and/or the opening degree of the pressure regulator valve based on two parameters, i.e., the inlet temperature and the torque of the compressor.
