Recently, a hydrogen-powered unmanned aerial vehicle (UAV) independently developed by Beihang University (BUAA) has set a new world record. During a nonstop flight test, the drone remained airborne for over 40 hours and covered more than 3,000 kilometers, establishing new global benchmarks for both endurance and range among hydrogen fuel cell-powered drones. This milestone marks a significant advancement in China’s capabilities in green aviation and new-energy UAV technologies.The drone utilizes a high-efficiency hydrogen fuel cell system as its primary power source, complemented by lightweight structural design and intelligent energy management algorithms, which collectively enhance energy efficiency. Compared to conventional lithium-ion batteries, hydrogen fuel cells offer higher energy density, faster refueling, and zero carbon emissions—making them ideal for long-endurance, long-range missions such as border surveillance, disaster monitoring, and communication relay.According to BUAA’s research team, this achievement not only validates the feasibility of hydrogen energy in aviation but also lays a technological foundation for future applications in urban air mobility, green logistics, and emergency response. As hydrogen infrastructure continues to expand, hydrogen-powered aircraft are poised to become a key component of the next-generation low-altitude economy.This breakthrough highlights the innovative strength of Chinese universities in cutting-edge technologies and underscores China’s commitment to a green, low-carbon development strategy.
近日，北京航空航天大学（北航）自主研发的氢动力无人机成功刷新了世界纪录。该无人机在一次不间断飞行测试中，持续飞行时间超过40小时，飞行距离突破3000公里，创下全球氢燃料电池无人机最长续航时间与最远航程的新纪录。这一突破标志着我国在绿色航空和新能源无人机技术领域迈出了关键一步。该氢动力无人机采用高效氢燃料电池系统作为主能源，结合轻量化结构设计与智能能量管理算法，显著提升了能源利用效率。与传统锂电池相比，氢燃料电池具有能量密度高、加注速度快、零碳排放等优势，特别适用于长航时、远距离任务场景，如边境巡逻、灾害监测、通信中继等。北航科研团队表示，此次纪录的实现不仅验证了氢能源在航空领域的可行性，也为未来城市空中交通、绿色物流及应急响应等应用场景提供了技术储备。随着氢能基础设施不断完善，氢动力飞行器有望成为下一代低空经济的重要组成部分。此次成就彰显了中国高校在前沿科技自主创新方面的实力，也体现了国家对绿色低碳发展战略的坚定推进。
