First ZEROe engine fuel cell successfully powers on | Airbus

In late 2023, the ZEROe teams powered on the iron pod, the future hydrogen-propulsion system designed for Airbus' electric concept aircraft. As well as the hydrogen fuel cell system, the iron pod contains the electric motors needed to spin a propeller and the units that control and keep them cool. Its successful power on at 1.2 megawatts is a pivotal step on Airbus' ZEROe roadmap to put a hydrogen-propulsion aircraft into service by 2035.
