  • Patent number: 11072249
    Abstract: A fuel gas pump of a fuel cell vehicle is fixed to a stack frame and a fuel cell stack via a first bracket and a second bracket so that a rotation axis of a motor is inclined to a reference line along a front-rear direction. The first bracket is fixed by passing a second fastening member through a first notch. The second bracket is fixed by passing a third fastening member through a second notch of a second arm. The first and second brackets are provided such that, when the fuel gas pump rotates, the third fastening member comes off from the second bracket at a timing different from a timing when the second fastening member comes off from the first bracket.

  • Patent number: 10479215
    Abstract: A fuel cell vehicle comprising: a hydrogen tank which is mounted on the vehicle so as to have a center axis generally parallel to a front/rear direction of the vehicle; a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage; an aftercooler placed between the hydrogen tank and the high-voltage electric component to cool compressed air; and a fuel cell stack which is supplied with the cooled compressed air.

  • Patent number: 9789755
    Abstract: A compressor, an intercooler, and a fuel cell stack are housed in a housing compartment. The compressor and the intercooler are connected with each other by upstream side piping, and the intercooler and the fuel cell stack are connected with each other by downstream side piping. The upstream side piping is formed from upstream side first and second pipe parts, and the downstream side piping is formed from downstream side first and second pipe parts. Movement of the compressor and fuel cell stack relative to the intercooler at the time of a heavy collision of the vehicle causes disconnection of the upstream side first and second pipe parts and disconnection of the downstream side first and second pipe parts, to thereby cause communication of the upstream side piping and the downstream side piping with an internal space of the housing compartment.
