To provide a suspension system that can efficiently lay out a shock absorber and various accessories in a fuel cell electric vehicle where a fuel cell is mounted in the vicinity of a floor portion of the body. In a suspension system of a fuel cell electric vehicle provided with a fuel cell mounted in the vicinity of a floor portion of the body, a motor is provided for generating a driving force of a vehicle based upon electric power supplied from the fuel cell. A motor unit is supported by a body frame so that the motor unit can be rocked for housing the motor and a shock absorber provided between the motor unit and the body frame. The shock absorber is arranged under the fuel cell.
