The invention discloses a proton exchange membrane fuel cell and gas turbine combined power generation system for an airplane and belongs to the field of airplane power generation systems. A proton exchange membrane fuel air outlet communicates with an air inlet of a combustor, and an air outlet of the combustor communicates with an air inlet of a turbine. High-temperature and high-pressure gas generated by the combustor enters the turbine to do work, a part of output work of the turbine is transmitted to an air compressor, and the residual part drives a generator to generate power. A proton exchange membrane fuel cell and the generator output direct current and alternate current, and by means of exchanging with a power transformation device, the direct current and the alternate current are converted into alternate current to be output. The proton exchange membrane fuel cell is adopted as electric power energy of the airplane, the proton exchange membrane fuel cell provides electric power for the airplane, unused energy including fuel cell residual gas provides power for turbine work through the combustor, in addition, the pressure ratio of the coaxial air compressor connected with the turbine is matched with the pressure ratio of the fuel cell, and in a whole, by means of the mixed power of the proton exchange membrane fuel cell and the gas turbine, efficiency is high, and reliability is high.
Description
technical field [0001] The invention belongs to the field of aircraft power generation systems; in particular, it relates to a proton exchange membrane fuel cell gas turbine combined power generation system for aircraft. Background technique [0002] The power system is an indispensable and important part of the spacecraft, and its reliability directly affects the life of the spacecraft. The spacecraft power supply should be selected according to the flight mission, spacecraft design life and power supply requirements. The development of spacecraft urgently needs a power system with high power, long life and high reliability. The quality of the power supply system has a large proportion in the spacecraft. The solar aircraft with very strict quality requirements requires high specific energy of the energy storage device. At present, only fuel cells can meet the requirements. [0003] The existing aircraft power supply system has complex structure, various forms and low reli...
