The invention discloses a power system of a hydrogen cell aircraft. The power system comprises a control system and a power supply system. The control system comprises a controller controlling runningof a motor. The power supply system comprises a hydrogen cell power supply system, a storage battery power supply system and a circuit to charge a storage battery; in the hydrogen cell power supply system, a current starts from the anode of a hydrogen cell, is converted into a rated voltage by a DC / DC converter, passes a first fuse, a first diode and a first switch, reaches the anode of the controller, and then starts from the cathode of the controller, passes the DC / DC converter and is connected to the anode of the hydrogen cell to form a complete loop; and in the storage battery power supply system, a current starts from the anode of the storage battery, passes a second fuse, a second diode and a second switch, reaches the controller, and is connected to the cathode of the storage battery via the controller to form a complete loop. The new power system which is environment-protective, high-efficiency and long-endurance is designed by using advantages of being pollution-free and high-efficiency of the hydrogen cell.
Description
technical field [0001] The invention relates to a power system, in particular to a hydrogen fuel cell aircraft power system. Background technique [0002] Electric aircraft use electric propulsion instead of internal combustion engine power, thereby gaining many advantages and unique qualities. The most prominent advantages are energy saving and environmental protection, high efficiency and low energy consumption, while achieving near zero emissions, low noise and vibration levels, and good ride comfort. It is a veritable environment-friendly aircraft. In addition, it also has the characteristics of safety and reliability (no explosion and fuel leakage), simple structure, easy operation and use, good maintainability / low cost, and good economy. There are also many advantages in design: the overall layout is flexible, and the optimal layout and unconventional / innovative layout can be adopted; aircraft with extraordinary performance can be designed to meet special purpose requ...
