Boeing announced today that it had successfully completed the first manned flight of a small, propeller driven plane powered by a hydrogen fuel cell. The hydrogen fuel cell produces only heat and water as a byproduct making a much greener aircraft.
The small two-seat plane made three test flights which took place in March at an airfield in Ocana south of Madrid Spain. The plane’s propeller is driven by an electric motor powered by the fuel cell.
The plane also has batteries to power the electric motor that are used to assist in take off. Once airborne the plane’s electric motor is powered by the fuel cells alone. The current flying time of the plane is only 45 minutes.
