Provided is a fuel cell system configured to: calculate a target stack supply flow rate based on a request from a fuel cell stack; calculate a compressor supply flow rate requested by stack based on a stack supply flow rate and the target stack supply flow rate; set a larger one of the compressor supply flow rate requested by stack and a lower limit flow rate, which is determined depending on an operation state of the fuel cell system, as a target compressor supply flow rate; control a compressor depending on the target compressor supply flow rate; control a bypass valve based on the stack supply flow rate and the target stack supply flow rate; fix the bypass valve when the stack supply flow rate is in a predetermined bypass valve fixing range having the target stack supply flow rate as a reference, and the stack supply flow rate becomes less than the target stack supply flow rate; and release the fixation of the bypass valve when the target compressor supply flow rate becomes more than the lower limit flow rate after the bypass valve is fixed. |
