The demonstrator aircraft is a Dimona motor glider built by Diamond Aircraft Industries of Austria. With a wingspan of 16.3 m (53.5 ft), the plane should cruise at about 100 km/hr (62 mph) using fuel-cell power.
"While Boeing does not envision that fuel cells will provide primary power for future commercial airplanes, demonstrations like this could pave the way for using this technology in small manned and unmanned aircraft," says Francisco Escarti, managing director Boeing Research and Technology (Europe).
