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.
