Fuel cell vehicle

There is provided a fuel cell vehicle that allows minimally suppressing damage of a fuel cell stack and a high voltage component as important components when the vehicle collides from a front side. An ion exchanger as a first component includes a tubular portion and a cap portion. When the front side of the fuel cell vehicle collides, the tubular portion deforms due to an impact load from a radiator as a second component moving toward the ion exchanger to buffer an impact from the radiator. The cap portion restricts additional deformation of a damper portion when the impact load from the radiator becomes a predetermined magnitude or more. A stack frame and a chassis are joined and fixed via mounts such that the stack frame is detached from the chassis due to the impact load from the radiator when the deformation of the tubular portion is restricted by the cap portion.
