Yey, at last a hydrongen fuel-cell powered electric plane that can do top speeds of 62mph!
Not your jet plane but still, you are flying very efficiently.
The plane is based on a two-seat Dimona motor-glider frame with a 16.3 metre (53.5 feet) wingspan. It was modified by BR&TE to incorporate a hybrid low emission engine, containing Intelligent Energy’s power dense Proton Exchange Membrane (PEM) fuel cell power system and lithium-ion batteries, to power an electric motor coupled to a conventional propeller.
Three test flights took place in February and March at an airfield near Madrid. Each time, the pilot climbed to an altitude of 1,000 metres(3,300 feet) above sea level using a combination of battery power and power generated by the hydrogen fuel cells, and continued in a straight path at the cruising altitude for 20 minutes at a speed of 100 km per hour (62 miles per hour) on power solely generated by the fuel cells.
