Compared to internal combustion engines, which can cause noise and vibration that can interfere with the operation of UAV sensors and payloads, fuel cell technology is quiet.
Additionally, compared to alternative fuels, internal combustion engines often have a substantially lower MTBF (Mean Time Between Failures), necessitating additional maintenance, spare parts, and labour.
In comparison to many internal combustion engines, which are less effective at higher altitudes due to the lower air density, hydrogen-powered drones are more efficient.
Small internal combustion engines are noisy, dirty, and have a strong thermal signature, and they only operate at their highest fuel efficiency within a specific range of conditions.
Batteries not only have a low energy density but also require a long time to recharge, with a charge cycle frequently taking much longer than the normal half-hour flight endurance that they offer. Hydrogen cylinders may be changed out in a matter of minutes, improving operating effectiveness.
Global UAV hydrogen fuel cell stack market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The JOUAV vertical take-off and landing (VTOL) fixed-wing UAV CW-25H was successfully delivered with a 330-minute flight time to the Beichuan flying base in Mianyang, Sichuan Province, China.
After they entered the twenty-first century, nations all over the world began to pay more and more attention to the new energy offered by hydrogen energy, with its benefits of high efficiency, pollution-free, and zero emissions.
The primary application of hydrogen energy is the hydrogen fuel cell, which is more convenient, safe, and does not emit secondary pollution than conventional lithium batteries.
Its energy density is two to three times greater than that of traditional lithium batteries. The hydrogen fuel cell offers reduced vibration and no corrosion compared to conventional internal combustion engines. It is among the top options for long-lasting drones.
In order to collaborate on the development of hydrogen-powered vertical takeoff and landing UAVs, JOUAV and Doosan Innovation signed a contract under which JOUAV would be in charge of the hydrogen-powered UAV platform system and Doosan would be in charge of the hydrogen-powered UAV fuel cell system. The hydrogen-powered technology proving aircraft made its first flight in the same year.
