PROBLEM TO BE SOLVED: To recover remaining energy from exhaust gas, to reduce the power consumption of a regenerator and to increase the efficiency of compressor power assistance by joining movable scrolls to both ends of a motor output shaft, and setting a pressure ratio of a scroll type compressor to the regenerator connected to an air feeding pipe and an exhaust pipe so that the pressure of the regenerator is lower by a value equivalent to the loss of the exhaust gas pressure. SOLUTION: The simplification of an air feeding mechanism and the rational cancellation of working propelling force are realized by symmetrically connecting a movable scroll 20 of a compressor to an eccentric crank shaft 12 joined in parallel to a motor output shaft Mc, and a movable scroll 40 of a regenerator to the opposite end. The number of turns of a movable coiled body 40b and a fixed coiled body 50b of the regenerator E is smaller by 1/4 turn than that of a movable coiled body 20b and a fixed coiled body 30b forming an working chamber 31 of the compressor C, so that the pressure loss in a fuel cell can be compensated. The regenerator E reduces a driving current without transmitting a negative torque to the motor output shaft Mc. The pressure ratio may be adjusted by the position and size of an introduction port 52. |
