A fuel cell vehicle comprises a fuel cell stack that is mounted in a housing box placed on a front or rear side of a passenger compartment. The fuel cell stack is housed in a stack casing, and the stack casing is mounted on a frame of the housing box via a stack mount. The stack mount includes: a stack-side bracket provided in the stack casing; a frame-side bracket provided in the frame; and a fixing member configured to fix the stack-side bracket and the frame-side bracket together. The stack mount has at least either one of: (a) a first structure in which a cutout portion is formed in the stack-side bracket on one side thereof which faces a proximal end portion, the proximal end portion being one of a front end portion and a rear end portion of the fuel cell vehicle which is closer to the housing box; or (b) a second structure in which a cutout portion is formed in the frame-side bracket on one side thereof which faces a distal end portion, the distal end portion being another one of the front end portion and the rear end portion of the fuel cell vehicle which is farther from the housing box.
