Abstract: An ion exchanger includes a housing, a tube member, and an ion exchange resin. The housing includes an inlet port and an outlet port. The tube member is arranged inside the housing. The ion exchange resin is arranged between the tube member and the housing. A first flow passage and a second flow passage are formed in the housing. The first flow passage is configured to cause the coolant that has flowed in through the inlet port to flow directly to the outlet port. The second flow passage is configured to cause the coolant that has flowed in through the inlet port and passed through the ion exchange resin to flow to the outlet port. The first flow passage and the second flow passage are formed to join together in a state of being oriented in a same direction toward the outlet port.

Abstract: 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.
