The invention belongs to the technical field of automobiles, and particularly relates to a hybrid power system with a natural gas engine and an SOFC working together. The system comprises a natural gas engine, an SOFC, a power battery, a natural gas tank, a turbine, a gas compressor, a driving motor and a gearbox. A natural gas inlet of the natural gas engine is connected with the natural gas tank, and an air inlet is connected with the gas compressor; the natural gas engine is connected with the turbine; the turbine is connected with the gas compressor; the anode of the SOFC2 is connected with the natural gas tank, and the cathode of the SOFC2 is connected with the gas compressor; the current output end of the SOFC is connected with the power battery and the wiring end of the driving motor; the input end of the gearbox is directly connected with a rotating shaft of the driving motor; a rotating shaft of the driving motor is connected with the output end of the natural gas engine through a clutch; and the output end of the gearbox is connected with a drive axle of the vehicle. The two power sources of the natural gas engine and the SOFC battery are combined, the advantages of the two power sources are effectively exerted, and therefore energy management is achieved, and oil consumption, emission and noise are reduced.

    本发明属于汽车技术领域,具体的说是一种天然气发动机与SOFC共同工作的混合动力系统。该系统包括天然气发动机、SOFC、动力电池、天燃气罐、涡轮机、压气机、驱动电机和变速箱;天然气发动机的天然气入口与天燃气罐连接,空气入口与压气机连接;天然气发动机与涡轮机连接;涡轮机与压气机连接;SOFC2的阳极与天燃气罐连接,阴极与压气机连接;SOFC的电流输出端与动力电池、驱动电机的接线端连接;变速箱的输入端与驱动电机的转轴直连;驱动电机的转轴与天然气发动机的输出端通过离合器连接;变速箱的输出端与车辆的驱动桥连接。本发明将天然气发动机、SOFC电池两种动力源结合,有效发挥各自优势,从而实现能量管理,降低油耗、排放、噪声。
