A fuel cell vehicle according to the present disclosure includes, in a front room: a fuel cell stack fixed to an upper part of a stack frame; a high voltage element fixed to an upper part of the fuel cell stack; and an ion exchanger that is arranged in front of the fuel cell stack and the high voltage element. The stack frame is provided with an inclined part, and when the ion exchanger is displaced rearward at the time of a frontal crash of the fuel cell vehicle, a rear part in a lower end of the ion exchanger is slid along an inclined surface of the inclined part and the ion exchanger is displaced in a diagonally upward direction, whereby the cap part of the ion exchanger is positioned on the upper side in the vertical direction with respect to the high voltage element.
