IT Home reported on November 13 that Dalian University of Technology announced today that a research team led by Associate Professor Mao Qing of the university's School of Chemical Engineering has successfully developed China's first 20 kg-class hydrogen-powered unmanned helicopter, employing both a pure hydrogen fuel cell and a hydrogen-lithium hybrid dual technology route. The development produced two operational models, equipped with 5L and 12L hydrogen cylinders respectively: the 5L-35MPa hydrogen-lithium hybrid model has an endurance of 1.5 hours, while the 12L-35MPa hydrogen fuel cell model reaches an endurance of up to 3 hours, a several-fold improvement over the roughly 30-minute endurance of conventional lithium-battery drones. At the core technology level, the team independently developed an air-cooled fuel cell power system, subjecting the core stack to rigorous testing under multiple operating conditions including temperature, humidity, and salt spray, confirming excellent system performance, stable operation, and strong environmental tolerance; the self-developed membrane electrode achieved a peak power density of 732mW/cm² at an operating voltage of 0.6V and can opera

Dalian University of Technology Successfully Develops China's First 20 kg-Class Hydrogen-Powered Unmanned Helicopter, Completing Offshore Cruise Mission in Force-6 Winds

IT之家, November 13: Dalian University of Technology announced today that a research team led by Associate Professor Mao Qing from the university's School of Chemical Engineering has successfully developed China's first 20 kg-class hydrogen-powered unmanned helicopter, covering both pure hydrogen fuel cell and hydrogen-lithium hybrid technology routes.

IT之家 has learned that this development has produced two operational models, equipped with 5L and 12L hydrogen cylinders respectively: the 5L-35MPa hydrogen-lithium hybrid model has an endurance of 1.5 hours, while the 12L-35MPa hydrogen fuel cell model reaches an endurance of up to 3 hours — a several-fold improvement over the roughly 30 minutes typical of conventional lithium-battery drones.

At the core technology level, the university's research team independently developed an air-cooled fuel cell power system, subjecting the core stack to rigorous testing under multiple operating conditions including temperature, humidity and salt fog, confirming excellent system performance, stable operation and strong environmental tolerance. Among these, the self-developed membrane electrode assembly stands out: at an operating voltage of 0.6V, peak power density reaches 732mW / cm², with stable operation at a high power density of 650mW / cm², and the stack achieves a gravimetric power density of 1.4 kW / kg. The project team independently developed the system control module, deeply integrating power system detection, spectroscopic diagnostics and intelligent control to achieve closed-loop linkage of detection-diagnosis-control, enabling efficient coupling and matching between the self-developed fuel cell and the aircraft platform.

Verified through practical test flights, this series of drones successfully completed an offshore cruise mission in force-6 winds, flying in a stable state with strong adaptability to complex environments, and can be widely applied in diverse scenarios such as urban inspection, offshore operations and mountain surveys.
