Chinese Scientists Develop 'Hydrogen Heart' to Double Drone Flight Time

Researchers at the Dalian Institute of Chemical Physics (DICP) have developed a breakthrough hydrogen fuel cell technology designed to significantly extend drone flight endurance.

The technology, dubbed a "hydrogen heart," utilizes a high-specific-power, cathode-closed, air-cooled stack. By moving away from traditional heavy cooling systems and limited lithium-ion batteries, this lightweight stack allows industrial drones to stay airborne nearly twice as long as current models.

During a successful test flight in Dalian on Sunday, the system demonstrated a specific power output of 1,970 W/kg. Chen Zhongwei, the project's technical director, confirmed that the technology has moved beyond the laboratory phase and is now ready for large-scale industrial application.

The "hydrogen heart" is expected to revolutionize sectors requiring long-endurance aerial coverage, including forest monitoring, precision agriculture, power grid inspections, and emergency disaster relief.
