Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] like figure 1 Shown is the system structure connection diagram of the present invention.
[0030] The fan provides air for the battery, and the oxygen in it is used as an oxidant and is fed into the fuel cell by the fan at a certain wind pressure. The hydrogen stored in the hydrogen cylinder is used as fuel, and enters the fuel cell through the pressure-reducing valve and the pressure-stabilizing valve. The exhaust gas generated by the battery reaction is discharged through the solenoid valve driven by the program-controlled drive module. There is hot circulating water in the water tank, which is used to circulate through the inside of the battery to take out the heat of the battery, and the water pump provides power for the circulating water. Aviation motor ESC, because the motor adopts ESC, it can achieve wide voltage input, and ca...

Abstract
The invention relates to a simplified proton exchange membrane fuel cell system for aviation. The simplified proton exchange membrane fuel cell system comprises: a hydrogen cylinder connected to a fuel cell through a pressure reducing valve and a pressure stabilizing valve, wherein hydrogen is used as a fuel, passes through the pressure reducing valve and the pressure stabilizing valve, and then enters the fuel cell; a fan for inputting air into the fuel cell, wherein oxygen in the air is used as the oxidant of the fuel cell; the fuel cell, wherein the fuel cell, a water box and a water pump form a closed loop, and the fuel cell is subjected to heat dissipating through circulating water; a gas discharge drive module connected to the fuel cell, wherein the tail gas generated by the fuel cell is discharged by controlling an electromagnetic valve; and a motor electronic speed control connected to the fuel cell and used for providing power source output for an aircraft. According to the present invention, based on the aerospace application environment, the control strategy and the system structure are simplified, the control scheme is optimized, the weight is reduced, and the performance and the stability are improved.
Description
technical field [0001] The invention relates to fuel cell modular integration technology, in particular to a simplified proton exchange membrane fuel cell system for aviation. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) has the advantages of high energy conversion efficiency, environmental friendliness, simple structure, and convenient operation, so it is widely used in many fields such as aerospace, new energy vehicles, and distributed power stations. [0003] PEMFC usually uses hydrogen as the anode fuel, air or oxygen as the cathode oxidant, and performs an electrochemical reaction at low temperature, and the reaction product is water. Although the battery reaction principle is simple, as a modular battery, it is necessary to integrate many executive components such as air supply, exhaust emission, power electric control, and waste heat discharge. For different application fields, there are different requirements for the operating conditions,...
