A gas-compression module for use in a fuel cell system includes an air compressor, a motor and an intercooler. The air compressor has a pump chamber for compressing gas. The motor has a drive shaft for driving the air compressor. The intercooler cools the compressed gas exhausted from the air compressor. The air compressor includes a first rotor and a main rotary shaft connected to the drive shaft of the motor for driving the first rotor. The air compressor also includes a second rotor and a driven rotary shaft driven by power transmitted from the main rotary shaft for driving the second rotor. The motor and the intercooler exist in an imaginary plane passing through an axis of the main rotary shaft and an axis of the driven rotary shaft. The center of gravity of the intercooler is located closer to the driven rotary shaft than that of the motor.
