Description

  The present invention relates to a fuel cell vehicle including a fuel cell stack that generates electric power by an electrochemical reaction between an oxidant gas supplied to a cathode side and a fuel gas supplied to an anode side and outputs electric power to a vehicle running load.

  For example, in a polymer electrolyte fuel cell, an electrolyte membrane / electrode structure (MEA) in which an anode side electrode and a cathode side electrode are disposed on both sides of an electrolyte membrane made of a polymer ion exchange membrane is sandwiched between separators. It has a power generation unit. This type of fuel cell normally constitutes a fuel cell stack by stacking a predetermined number (for example, several hundred) of power generation units, and the fuel cell stack is used as an in-vehicle fuel cell stack. Yes.

  In a fuel cell vehicle equipped with the above fuel cell stack, for example, when an impact from the front acts on the fuel cell stack, it is necessary to protect the fuel cell stack.

  Therefore, for example, a vehicle disclosed in Patent Document 1 is known. As shown in FIG. 12, this vehicle is an electric vehicle, and a drive motor 2 is disposed below the engine compartment 1.

  In the engine compartment 1, a fuel cell 3 is disposed vertically above the drive motor 2, and one end side of the fuel cell 3 is configured to be rotatable in the vehicle height direction via a support shaft 4. ing. A bracket 5 is provided on the other end side of the fuel cell 3, and the bracket 5 is joined to the upper surface of the drive motor 2.

  Therefore, when the vehicle receives an impact from the front, the load 6 moves rearward due to the impact and collides with the drive motor 2. The drive motor 2 moves rearward and vertically downward by the collision of the load 6 (see the broken line position to the solid line position in FIG. 12). For this reason, since the bracket 5 is separated from the driving motor 2, the fuel cell 3 rotates vertically downward with the shaft of the support shaft 4 as a fulcrum. Therefore, when the vehicle receives an impact from the outside, the fuel cell 3 is supposed to suppress the collision with the dash panel DP.

  In the fuel cell vehicle 10 configured as described above, the operation of the fuel cell system 60 will be described below.

And can move linearly along the rail members 42a and 42b together with the slide plate 48. For this reason, it is possible to reliably protect the fuel cell stack 14 with a simple configuration.

  Furthermore, on the slide plate 48, in particular, a hydrogen supply system component, a high-pressure component, an enclosure, and the like can be mounted as the mounting component 104. Therefore, there is an advantage that it is possible to favorably avoid damage to the mounted component 104.

  Furthermore, in the first embodiment, the fuel cell stack 14 can move linearly along the rail members 42 a and 42 b that are guide members via the slide mechanism 46.
