摘要： A control method includes acquiring the operation stop request of the fuel cell system, acquiring a next vehicle operation start timing, and calculating a first energy cost and a second energy cost at a predetermined timing after acquiring the operation stop request and the next vehicle operation start timing. The first energy cost is an energy cost required from the predetermined timing to completion of warming up of the fuel cell when a warm-up control is executed using the heater in accordance with the next vehicle operation start timing after the stop control is executed. The second energy cost is an energy cost required when an operation of the fuel cell is continued so as to maintain a temperature of the fuel cell at a warm-up temperature from the predetermined timing to the next vehicle operation start timing. The control method includes continuing the operation of the fuel cell such that the temperature of the fuel cell is maintained at the warm-up temperature while the first energy cost is larger than the second energy cost after the operation stop request is acquired.

摘要： A fuel cell system sets the larger one of a stack request compressor supply flow rate calculated based on a request of a fuel cell stack and a system request compressor supply flow rate calculated based on a request by the fuel cell system as a target compressor supply flow rate and controls a compressor according to the target compressor supply flow rate. The fuel cell system also controls a bypass valve based on a stack supply flow rate and a target stack supply flow rate to be supplied to the fuel cell stack. The fuel cell system fixes the bypass valve or limits the drive of the bypass valve when the system request 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.
