Abstract
A fuel cell system includes a fuel cell, a motor, a scroll type compressor connected to the air feeding pipe of the fuel cell and a scroll type regenerator connected to the air exhaust pipe of the fuel cell. The compressor and the regenerator share a movable scroll which is operatively coupled to the motor output shaft. The movable scroll has a common base plate, a first scrolling wall arranged on one side of the common base plate to engage with a scrolling wall of a stationary scroll of the compressor, and a second scrolling wall arranged on the other side of the common base plate to engage with a scrolling wall of a stationary scroll of the regenerator. This arrangement simplifies the structure and facilitates power assistance to the compressor.
