The High-Specific-Power Cathode-Closed Air-Cooled Stack, a fuel cell developed by the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Science (CAS), has passed the scientific and technological achievement assessment.
Dubbed the “hydrogen heart” for industrial-grade drones, this new battery stack combines lightweight design, high-power output, and air-cooling technology, and is capable of doubling the flight endurance of industrial-grade drones.
With the rapid growth of the low - altitude economy , various issues, including the limited flight time of conventional lithium batteries and the heavy weight of current fuel cell systems, have emerged as significant obstacles hindering the progress of the drone industry.
A hydrogen-powered drone equipped with a new battery array successfully completed a test flight on in Dalian, Liaoning Province, China, demonstrating excellent performance on key indicators.
This air-cooled battery array achieves a specific power of 1,970 watts per kilogram and an areal power density of 1.15 watts per square centimeter.
This "hydrogen heart" has achieved the transition from laboratory development to large-scale application, said Chen Zhongwei, technical leader of the project and director of the State Key Laboratory for Catalysis at DICP.
This technology has been applied in a variety of scenarios including forestry, agriculture, power grid inspection, and emergency response missions.
