IEC 62282-4-202:2023 covers performance test methods of fuel cell power systems intended to be used to power unmanned aircrafts, including general requirements, start-up, shutdown, power output, continuous running time, electric efficiency, data transmission, warning and monitoring, environmental compatibility, etc. The scope of this document is limited to electrically powered unmanned aircrafts with a maximum take-off mass not exceeding 150 kg (i.e. level 5 or lower unmanned aircrafts (UAs)). This document applies to fuel cell power systems with a rated output voltage not exceeding 220 V DC for outdoor use. This document applies only to compressed gaseous hydrogen-fuelled fuel cell power systems.
