  • Patent number: 9688130
    Abstract: A fuel cell vehicle capable of preventing illegally access by using a tool to a piping fitting connecting fuel piping and a valve module to each other without increasing the number of components. The fuel cell vehicle includes an electric motor, a fuel cell supported by a frame to supply electric power to the electric motor, a fuel tank supported by the frame to store fuel to be supplied to the fuel cell, a valve module disposed below a cross member and behind the fuel tank, and a piping fitting connecting fuel piping to the valve module. The valve module includes a cut-out stepped portion provided in a side-face side of an upper portion of the valve module. The piping fitting is attached to the cut-out side face, the piping fitting being disposed between the cross member and the cut-out top face in a vehicle vertical direction.

  • Publication number: 20160079618
    Abstract: There are provided a hydrogen tank for compressed storage of hydrogen gas, as fuel gas, at high pressures; a fuel cell stack for generating and supplying power using the hydrogen gas from the hydrogen tank; a hydrogen supply path interconnecting the hydrogen tank and the fuel cell stack; a shutoff valve for allowing supply of the hydrogen gas from the hydrogen tank by opening or closing the hydrogen supply path; a fuel supply valve, situated downstream of the shutoff valve, with respect to a supply direction of oxygen gas, for allowing supply of hydrogen gas to fuel cell stack; and an ECU for controllably causing the fuel supply valve to assume its closed state and the shutoff valve to assume its opened state during filling the hydrogen tank with hydrogen gas.
