The high-specific power cathode-closed-air-cooled stack,
developed by the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences,
has passed the SciTech Achievement Appraisal, dubbed the hydrogen heart for industrial-grade drones.
The new 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,
issues including the limited flight time of traditional lithium batteries and the heavy weight of current fuel cell systems
are emerging as major constraints, hindering the progress of the drone industry.
A hydrogen-powered drone equipped with this new stack recently completed a test flight in Dalyan
in northeast China's Liaoning province, demonstrating excellent performance on key indicators.
The air-cooled stack achieved a specific power as high as 1,970 watts per kilogram and an area power density
of 1.15 watts per square centimeter.
Chen Zhongwei, the project's technical lead,
said this hydrogen heart has achieved the transition from laboratory development to large-scale application.
The technology has already been deployed in scenarios including forestry,
