April 2007 — An unmanned hydrogen fuel cell powered “jet-like” UAV made history this week as it took to the skies over the hills of Bern, Switzerland. The “Hyfish” astonished its creators as it flawlessly performed vertical climbs, loops and other aerial acrobatics at speeds reaching 200 km/h. The successful maiden flight was the result of one and a half years of cooperative development between the German Air & Space Center (Deutsches Zentrum fuer Luft-und Raumfahrt) and a number of international partners including Smartfish for the plane design, Druckon, Baltico, and Teknizentrum Ainet. A record performance 1kW fuel cell and hydrogen system weighing just 3kg and capable of powering the small jet was supplied by Horizon Fuel Cell Technologies of Singapore: www.horizonfuelcell.com
