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 comprising: a fuel cell configured to be supplied with a fuel and air to generate an electric power; a combustor configured to combust an off-gas discharged from the fuel cell to produce a combustion discharged gas; a fuel heating part configured to heat the fuel to be supplied to the fuel cell by the combustion discharged gas; an air heating part configured to heat the air to be supplied to the fuel cell by the combustion discharged gas; an anode-side distribution passage configured to distribute the combustion discharged gas to the fuel heating part; a cathode-side distribution passage configured to distribute the combustion discharged gas to the air heating part; and a discharged gas distribution ratio adjustment part configured to adjust a discharged gas distribution ratio, the discharged gas distribution ratio being a ratio of an anode-side combustion discharged gas flow rate to a cathode-side combustion discharged gas flow rate, the anode-side combustion discharged gas flow rate being a flow rate of the combustion discharged gas that flows in the anode-side distribution passage, the cathode-side combustion discharged gas flow rate being a flow rate of the combustion discharged gas that flows in the cathode-side distribution passage, wherein the discharged gas distribution ratio adjustment part is configured to reduce the discharged gas distribution ratio according to an increase in a supply air flow rate as a flow rate of the air to be supplied to the fuel cell.

摘要： According to a control method for a hybrid vehicle that is caused to run by a drive motor as a load being supplied with electric power of a battery and electric power generated by an electric generator, a total distance to empty is calculated on the basis of a shortage of a generating power output of the electric generator with respect to a required running power output and an amount of charge remaining in the battery. Specifically, a length of time for which the shortage of the generating power output of the electric generator with respect to the required running power output is covered by the amount of charge remaining in the battery is calculated, and a distance that the hybrid vehicle can run for this length of time is set as a total distance to empty.
