Prospects for application of liquid hydrogen in unmanned aerial vehicles
An analysis is conducted on the working mechanism and performance constraints of conventional hydrogen fuel cells,and liquid hydrogen is presented as a substitute energy source.A detailed explanation of the liquid hydrogen fuel cell's operation is provided.Based on data from flight tests,a comparison of the endurance of hydrogen and liquid hydrogen fuel cells is con-ducted in order to confirm the endurance of the latter.According to test results,liquid hydrogen fuel cells have more endurance than typical hydrogen fuel cells.As a result,UAVs powered by liquid hydrogen fuel cells can fly farther and for longer periods of time.There are many potential uses for liquid hydrogen in the UAV industry.Although its high energy density and superior en-durance make it an attractive fuel option for UAVs in the future,more research needs to be done on concerns like storage and transit safety.
