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.
