Definitions
- the fuel cell system fixes the bypass valve or drives the bypass valve when the system required compressor supply flow rate is set as the target compressor supply flow rate and the stack supply flow rate becomes smaller than the target stack supply flow rate. Restrict.
- the first flow sensor 41 is provided in the cathode gas supply passage 20 upstream of the cathode compressor 23.
- the first flow rate sensor 41 detects the flow rate of the cathode gas supplied (sucked) to the compressor 23 (hereinafter referred to as “compressor supply flow rate”).
- the stack request compressor supply flow rate calculation unit 103 determines that the stack request compressor supply flow rate is greater than the dilution request compressor supply flow rate. The integration operation that becomes smaller is stopped.
- the cathode compressor is controlled so that the actual compressor supply flow rate becomes the dilution request stack request compressor.
- the compressor supply flow rate becomes constant (FIG. 7B). Since the actual stack supply flow rate is larger than the target stack supply flow rate from time t11 to time t12 (FIG. 7A), the calculation of deviation time integral in the stack required compressor supply flow rate calculation unit 103 is stopped. . Therefore, the stack required compressor supply flow rate is also constant as the dilution required compressor supply flow rate (FIG. 7B).
- the target compressor supply flow rate is set as the target compressor supply flow rate in the target compressor supply flow rate setting unit 104, in the stack required compressor supply flow rate calculation unit 103, Only when the actual stack supply flow rate is smaller than the target stack supply flow rate (when it is necessary to increase the stack required compressor flow rate), the time integration of the deviation between the target stack flow rate and the actual stack flow rate is performed. When the actual stack supply flow rate is larger than the target stack supply flow rate (when the stack required compressor flow rate needs to be reduced), the time integration of the deviation between the target stack flow rate and the actual stack flow rate is stopped. .
