Chinese Scientists Develop Hydrogen Hybrid Power for Industrial Drones

It is learned from Xinhua News Agency that Chen Zhongwei, director of the National Key Laboratory of Energy Catalytic Conversion at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, led a scientific research team to independently develop high-specific energy hydrogen hybrid power supplies for industrial-grade. The drone recently made a successful test flight.

This scientific research achievement will effectively solve the bottleneck problem of short battery life of industrial drones. At present, electric drones use lithium batteries as the mainstream power source, but they still have shortcomings such as short endurance and poor adaptability to low-temperature environments.

The hydrogen hybrid power supply developed by the team has the advantages of high specific energy, high reliability, and wide temperature range, and is commonly used in medium-sized fixed-wing and large multi-rotor drones. According to Chen Zhongwei, the team develops fuel cells and lithium battery coupled power supply systems in a systematic full-chain model. In addition to the above characteristics, it also has the advantage of long battery life.

The high specific energy hydrogen hybrid power supply developed by the team has a specific energy of 600 watt hours per kilogram and can be used at ambient temperatures of minus 20°C to 40°C. At the same time, the team will continue to develop the next generation of hydrogen hybrid power supply technology. Combining high-specific power stack design technology and high-energy density hydrogen source technology, the specific energy of the power supply will exceed 800 watt-hours per kilogram, and the application environment temperature range will be expanded to Minus 40℃-60℃.
