GB/T 38954-2020

This standard specifies the technical requirements, test methods, inspection rules, and marking, packaging, transport, and storage for hydrogen fuel cell power systems used in unmanned aerial vehicles (UAVs). It applies to the design, manufacturing, and quality verification of fuel cell systems that provide primary or auxiliary electrical power for multi-rotor, fixed-wing, and hybrid UAVs. The standard ensures safety, performance, and reliability in aerospace applications, particularly for long-endurance or high-altitude operations where hydrogen fuel cells replace or supplement batteries.
