Abstract
A fuel cell vehicle which a fuel cell stack is mounted on comprises a stack case that is configured to place the fuel cell stack therein; mounts that are configured to fix the stack case to a vehicle body; ribs, each being provided to be extended from a position adjacent to the mount across an upper surface of the stack case; and a damping member that is provided between adjacent ribs on the upper surface of the stack case. The damping member is a material formed by applying an aluminum sheet on butyl rubber. This configuration reduces the noise and damps the vibration.
Claims5
A fuel cell vehicle which a fuel cell stack is mounted on, the fuel cell vehicle comprising:
- a stack case that is configured to place the fuel cell stack therein;
- at least one mount structure that is configured to fix the stack case to a vehicle body;
- a rib that is provided to be along a path from a position adjacent to the mount structure across an upper surface of the stack case;
- and
- a damping member that is provided in a location that is at least part of the upper surface of the stack case other than a location area of the rib, the damping member being configured to suppress mechanical vibration.
A method of mounting a fuel cell stack on a fuel cell vehicle, comprising:
- providing a mount structure on an edge portion of a stack case configured to place the fuel cell stack therein, and providing a rib on an upper surface of the stack case along a vehicle front-rear direction to be extended from a position adjacent to the mount structure;
- providing a damping member in a location that is at least part of the upper surface of the stack case other than a location area of the rib, the damping member suppressing mechanical vibration;
- and
- fixing the stack case which the fuel cell stack is placed in to a vehicle body by means of the mount structure.
