Airbus has successfully tested a fuel cells system in flight. For the first time on a civil aircraft this innovative energy source powered the aircraft’s back-up hydraulic and electric power systems. The test conducted in February is part of Airbus’ overall plans for an eco-efficient aviation industry. It supports the on-going research to evaluate the potential use and environmental benefits of fuel cell technology and zero emissions power generation in civil aviation.
During the test, the hydrogen and oxygen based fuel cell system generated up to 20 Kilo Watts (kW) of electrical power. The emission free fuel cell system generates water as a “waste” product. The fuel cell system powered the aircraft’s electric motor pump and the back-up hydraulic circuit and also operated the aircraft’s ailerons. The system’s robustness was confirmed at high gravity loads (“g” loads) during turns and zero gravity aircraft manoeuvres. During the flight test, the fuel cells produced around 10 litres of pure water.
