PROBLEM TO BE SOLVED: To provide a fuel cell gas supply system and a fuel cell system capable of efficiently eliminating freezing of a hydrogen pump.SOLUTION: A fuel cell gas supply system comprises a hydrogen pump, an air compressor, and a driving device for driving the hydrogen pump and the air compressor. The driving device comprises a drive motor for driving the hydrogen pump and the air compressor, a differential planetary gear mechanism for outputting power from the output shaft of the drive motor to the hydrogen pump and the air compressor, a unidirectional rotation transmitting portion that is engaged with the output shaft of the drive motor and that inputs only the power in the rotational direction of one of the drive motors to the differential planetary gear mechanism in the acceleration direction, and a second direction rotation transmitting portion that is engaged with an output shaft of the drive motor and that inputs only the power in the other rotation direction of the drive motor to the differential planetary gear mechanism in the deceleration direction. When the hydrogen pump is frozen, the drive motor is rotated in the other rotation direction.SELECTED DRAWING: Figure 5
