  • Publication number: 20190270392
    Abstract: 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.

  • Patent number: 10381842
    Abstract: A power supply system of an embodiment has a plurality of power conditioners, an acquisition device, and a search instruction generator. The power conditioners convert a form of electrical power generated by a plurality of electrical generators into a different form of electrical power. The acquisition device acquires a respective information regarding power output from each of the plurality of power conditioners. The search instruction generator generates and outputs an operating point search instruction to one or more power conditioners being lower in a ratio of output power with respect to a reference power by at least a prescribed degree than one or more different power conditioners, wherein the reference power is given, based on the maximum output power or rated power of the corresponding electrical generator, or based on the maximum output power or rated power of the power conditioner.
