Abstract

The invention discloses an aircraft hydrocarbon fuel external reformed fuel cell gas turbine combined power generation system. The external reforming hydrogen production is performed for a hydrocarbon fuel in the power generation system to obtain hydrogen for a fuel cell. An external reforming machine and a water circulating bypass are added. The advantages of two power systems of the fuel cell and a gas turbine are combined; the efficiency of the fuel cell, the product composition and the fuel type of the gas turbine are reasonably matched; the tail gas temperature of the fuel cell and the front temperature of the gas turbine are reasonably matched; the pressure ratio of a gas compressor and the working pressure of the fuel cell are reasonably matched; and the power of the gas turbine and the power of the gas compressor are reasonably matched, so that the utilization efficiency of an aircraft fuel is improved. An all-electric aircraft is low in heating and part wear, so that the system reliability is improved; and the system is convenient to produce, install, use and maintain.

Description

technical field [0001] The invention belongs to the field of aircraft power generation systems; in particular, it relates to an aircraft-used hydrocarbon fuel external reforming fuel cell-gas turbine combined power generation system. Background technique [0002] With the increase of the flight time of the aircraft, the energy demand of the aircraft has become a bottleneck restricting the development of the aircraft. How to improve aircraft fuel efficiency while keeping the airframe compact has become a research hotspot. Fuel cells are valued by various countries because of their advantages of environmental protection and high fuel utilization efficiency. After years of development, gas turbine technology has been relatively mature, and the emissions of various pollutants are relatively low. It has been found that a large amount of waste heat is wasted in high-temperature fuel cells. High-grade waste heat allows it to form a hybrid device system with a gas turbine, thereby...
