Provided is a fuel cell system, including a fuel cell stack, a compressor, a cathode flow passage, a bypass flow passage branching from the cathode flow passage, thereby bypassing the fuel cell stack, a bypass valve configured to adjust a bypass flow rate, a stack flow rate sensor configured to detect a flow rate supplied to the stack, a compressor flow rate sensor configured to detect a flow rate taken into the cathode compressor, a required stack flow rate calculation unit configured to calculate a flow rate necessary for the stack depending on a state of a fuel cell, a required compressor flow rate calculation unit configured to calculate a flow rate which the compressor controls to flow depending on a requirement different from the requirement by the stack, and a control unit configured to control, when the flow rate required from the compressor is more than the flow rate required by the stack, the compressor based on the flow rate required from the compressor and a compressor flow rate detected by the compressor flow rate sensor, and control the bypass valve based on the flow rate required by the stack and a stack flow rate detected by the stack flow rate sensor. |
