    摘要： In a fuel cell system in which load electric power is supplied from a fuel cell and a secondary battery, intermittent operation is performed, that is, operation of the fuel cell is stopped and the load electric power is supplied from the secondary battery in a low load region. At this time, a threshold value for stopping and starting the operation of the fuel cell is adjusted according to open circuit voltage. Thus, it is possible to prevent fuel from being unnecessarily consumed in order to maintain the open circuit voltage at a predetermined value when the operation of the fuel cell is stopped, and to improve response of the fuel cell when the operation of the fuel cell is restarted after the open circuit voltage has decreased in the fuel cell that has stopped generating electric power.

    摘要： A maximum output of a fuel cell and a capacitance of a capacitor are set so as to be near a point at which a lower limit (a solid line “A” in FIG. 2) of a range in which a first condition is satisfied intersects a lower limit (a dashed line “B” in FIG. 2) of a range in which a second condition is satisfied. In the first condition, full acceleration at start time for obtaining a predetermined high vehicle speed by starting a vehicle at the maximum acceleration required of the vehicle can be repeatedly performed. In the second condition, full acceleration at a medium vehicle speed for increasing a vehicle speed from a medium vehicle speed by approximately 30 km/h at the maximum acceleration required of the vehicle can be repeatedly performed. Then, the fuel cell and the capacitor of this performance are mounted on the electric vehicle. As a result, it is possible to use the fuel cell and the capacitor both of whose performance is suitable for dynamic characteristics required for the vehicle, enhance the energy efficiency, and reduce the cost of the electric vehicle.

    摘要： A first hybrid vehicle (10A) is connected to a house-side connector (40). A second hybrid vehicle (10B) is connected to the first hybrid vehicle (10A), and they are connected in parallel within the first hybrid vehicle (10A) with respect to a house load (20). When a commercial system power source (50) is interrupted, an automatic switching circuit (30) is activated, and the house load (20) receives electric power from the first and second hybrid vehicles (10A, 10B). The first hybrid vehicle (10A) determines allocations of the amounts of electric power supply from the first and second hybrid vehicles (10A, 10B) based on the amount of the house load (20) and on the residual amounts of fuel in the first and second hybrid vehicles (10A, 10B).
