The invention relates to a parallel aviation hybrid power system based on proton exchange membrane fuel. The parallel aviation hybrid power system comprises a proton exchange membrane fuel cell subsystem; the aero-engine subsystem comprises an air inlet channel, an air compressor, a combustion chamber, a turbine and an exhaust nozzle, the air compressor is used for compressing air fed by the air inlet channel, then one part of the air is led out and fed into the proton exchange membrane fuel cell subsystem, and the other part of the air is discharged to the combustion chamber; the anode tail gas generated by the proton exchange membrane fuel cell subsystem also returns to the combustion chamber, and the cathode tail gas and the outlet tail gas generated by the combustion chamber are fed into the turbine together and then are discharged to the atmosphere through a tail nozzle. Compared with the prior art, cooperative work of the proton exchange membrane fuel cell and the aero-engine under the wide-area working condition of an aircraft is achieved, the system efficiency can be effectively improved, therefore, oil consumption of the engine is reduced, and wide application prospects are achieved.

    本发明涉及一种基于质子交换膜燃料的并联式航空混合动力系统,包括:质子交换膜燃料电池子系统;航空发动机子系统,其包括进气道、压气机、燃烧室、涡轮、尾喷管,所述压气机用于将进气道送入的空气压缩后,一部分引出送入质子交换膜燃料电池子系统,另一部分排出至燃烧室,所述质子交换膜燃料电池子系统产生的阳极尾气还返回所述燃烧室,阴极尾气则连同所述燃烧室产生的出口尾气一起送入所述涡轮,再经尾喷管排至大气。与现有技术相比,本发明实现了飞机宽域工作条件下质子交换膜燃料电池与航空发动机的协同工作,可以有效提高系统效率,从而降低了发动机油耗,具有广阔的应用前景。
