1. Clean and environmentally friendly, weak infrared radiation: no pollution, no noise during operation, weak infrared radiation when generating electricity at room temperature;

　　2. High energy density and strong endurance: much higher than lithium-ion batteries, with long endurance;

　　3. High energy conversion efficiency: up to 60%, more than twice that of internal combustion engines, thermal power, and solar power generation.

　　Traditional lithium-ion unmanned aerial vehicles experience significant capacity degradation and loss of mission capability after being charged and discharged dozens of times. Taking a domestic company's research and application in unmanned aerial vehicles as an example, the energy density of its fuel cell power system reaches 600wh/kg, which is more than three times that of the best lithium-ion battery unmanned aerial vehicle system currently available. In terms of range, drones are equipped with high-density fuel modules, which can easily achieve an ultra long endurance of more than 3 hours, far exceeding the current market's drone flight range by about 15-25 minutes.

　　It is foreseeable that the next 5-10 years will be a concentrated explosive period for the hydrogen fuel industry. With the rapid development of the industry, the cost of fuel cells will gradually decrease, which will help further promote the industrialization of long-range unmanned aerial vehicles. The industry has broad prospects.
