[0002] In recent years, various types of drones have been widely used in the fields of aerial photography and mapping, power inspection, express delivery, news reporting, disaster relief, battlefield information perception and reconnaissance and strike, which has greatly expanded the use of drones. Major countries are actively expanding the industry application of drones and vigorously developing drone technology. At present, most small and medium-sized drones are powered by polymer lithium-ion batteries, and their range is limited by the energy density of lithium-ion batteries.

[0003] Some researchers use fuel cells as a power source for small and medium-sized drones because they have the advantages of high energy density, high power density, and low emissions. However, conventional fuel cells use a stacked stack structure, which consists of several fuel cell monomers forming a rectangular stack. For small and medium-sized drones, the rectangular stack and its auxiliary components will undoubtedly occupy a large amount of effective space inside the body, causing serious space adaptation problems.

[0004] To this end, a new type of fuel cell component is needed that can effectively utilize the narrow and irregular space inside small and medium-sized UAVs, which is of great significance to improving the space utilization of small and medium-sized UAVs. Summary of the invention
