Fuel cell vehicle

A fuel cell vehicle comprising, 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 and removes ions included in a cooling liquid, the cooling liquid cooling the fuel cell stack, wherein
• the ion exchanger includes a main body part and a cap part that is provided on an upper side of the main body part and is more rigid than the main body part is,
• the stack frame is protruded further forward than the fuel cell stack is and includes an inclined part on an upper side of the protruded part, and
• an inclined surface of the inclined part is inclined rearward with respect to an upper side in a vertical direction, 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 the 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.
