Abstract

The invention belongs to the field of aviation power of clean energy, and discloses a fuel cell and gas turbine hybrid cycle power generation system which comprises a fuel tank, a gas turbine subsystem, a fuel cell subsystem, a control subsystem and an electric energy system. In the first working mode, fuel in a fuel tank enters the gas turbine subsystem, and the gas turbine subsystem converts energy generated after fuel combustion into electric energy to be stored in the electric energy system. In the second working mode, fuel of the fuel tank enters the fuel cell subsystem, the fuel cell subsystem converts chemical energy of the fuel into electric energy to be stored in the electric energy system, the remaining anode waste and cathode waste enter the gas turbine subsystem to be combusted, and energy generated after fuel combustion is converted into electric energy to be stored in the electric energy system; and the control subsystem is used for switching the two working modes. Compared with a traditional gas turbine engine system, the fuel utilization rate of the power generation system architecture is increased by 43% or above, the fuel consumption is reduced by 75% under the same power generation requirement, matched electric power can be directly output according to the power supply requirement needed by airborne equipment, and the requirement for adjusting large-amplitude fluctuation of the electric load of an aircraft in real time is met.
