摘要： A fuel cell system includes an air pump configured to supply air to a fuel cell, and a discharge flow rate determination unit which determines a discharge flow rate of the air pump when warming up the fuel cell, in accordance with a speed of a vehicle in which the fuel cell and the air pump are installed, or a required drive output of the vehicle. The discharge flow rate determination unit increases the discharge flow rate in the case that the speed or the required drive output is greater than or equal to a predetermined threshold value, and decreases the discharge flow rate in the case that the speed or the required drive output is less than the predetermined threshold value.

摘要： A fuel cell vehicle includes a fuel cell, an oxygen-containing gas supply apparatus, and an ECU. A pump of the oxygen-containing gas supply apparatus is a shaft floating type air pump having a rotatable element. The rotatable element floats from a wall around the rotatable element, as a result of rotation of the rotatable element. The ECU includes a traveling permission determination instruction unit. The traveling permission determination instruction unit determines whether or not a predetermined condition indicative of a floating state of the rotatable element is satisfied, and if the predetermined condition is satisfied, permits traveling of the fuel cell vehicle, and if the predetermined condition is not satisfied, restricts traveling of the fuel cell vehicle.

摘要： A control device includes a first accumulation unit configured to accumulate first energy, a second accumulation unit configured to accumulate second energy different from the first energy, and a supply unit configured to supply either or both of second energy obtained by converting first energy accumulated by the first accumulation unit and second energy accumulated by the second accumulation unit to an external device. The amount of second energy that is supplied from the supply unit to the external device is calculated on the basis of the amount of second energy supplied to a drive unit via the supply unit to move the moving body to a destination, the amount of first energy accumulated by the first accumulation unit, and the amount of second energy accumulated by the second accumulation unit, and a display device is caused to display a supply available time according to the calculated amount of second energy.

摘要： A first power source system includes a first motor control section that controls at least torque of a drive motor. When a temperature of an FC is less than or equal to a prescribed temperature Th and a demand for high output is made to the drive motor, the first motor control section limits the torque of the drive motor to be lower than a maximum torque that can be output by the drive motor, and continuously implements this torque limitation.
