To provide a fuel cell vehicle in which a fuel cylinder and a fuel cell stack are arranged so that the barycentric position is kept low and load is appropriately shared between the front and rear wheels. The fuel cylinder is mounted further forward than a seat, at a recumbent attitude inclined such that the shut-off valve side faces to the rear and the shut-off valve end is higher than the other end. The fuel cell box is positioned below the fuel cylinder between the pair of left and right lower frames and is fixed by being suspended from brackets provided at two places on the left and right upper frames, so as to overlap and run along a line connecting a rotational axis of the front wheel FW and the rotational axis of the rear wheel.
