What is claimed is: 1. A fuel cell vehicle comprising: a vehicle body having a floor frame; front wheels; rear wheels; a fuel cell that generates electricity by the electrochemical reaction of hydrogen and oxygen; and a subframe on which the fuel cell is mounted, being attached to the lower side of the floor frame and has a pair of side frames that extend in the fore-aft direction of the vehicle body; wherein the lower end of each side frame is formed to have a recess portion so that the portion located substantially midway between the front wheels and the rear wheels is the highest point from the tire-ground contact surface. 2. A fuel cell vehicle according to claim 1, further comprising a plurality of cross-members that extend in the width direction of the vehicle body to couple the side frames, wherein each of the side frames has an upper side frame and a lower side frame, with the upper side frame and the lower side frame sandwiching and fixing the end portions of the cross-members. 3. A fuel cell vehicle according to claim 2, wherein the upper side frames, the lower side frames, and the end portions of the cross-members are fastened to the floor frame by a common bolt. 4. A fuel cell vehicle according to claim 1, further comprising: a plurality of cross-members that extend in the width direction of the vehicle body to couple the side frames; and an underguard that is provided in front of the subframe and has a shape that slopes downward toward the rear of the vehicle body, wherein the vehicle body has a vehicle-body frame that extends in the width direction, and wherein the front edge of the underguard is coupled to the vehicle-body frame, and the rear edge of the underguard is coupled to the cross-member disposed closest to the front of the vehicle body. 5. A fuel cell vehicle according to claim 1, further comprising: a second subframe attached to the lower side of the floor frame, separate from the subframe in the fore-aft direction of the vehicle body; and a coupling member that couples mutually approaching portions of the subframe and the second subframe. 6. A fuel cell vehicle according to claim 5, further comprising a hydrogen tank which stores pressurized hydrogen to be supplied to the fuel cell, being mounted on the second subframe. 7. A fuel cell vehicle according to claim 5, further comprising a motor which drives at least one of the front wheels and rear wheels, being mounted on the second subframe. 8. A fuel cell vehicle according to claim 5, further comprising a plurality of cross-members that extend in the width direction of the vehicle to couple the side frames, wherein the coupling member is coupled to one of the cross-members disposed at a position closest to the second subframe.
