Hyfish
Hyfish is a model hydrogen powered aeroplane developed by Koni Schafroth. The model has successfully passed test flights under battery power and Smartfish is going forward with development to a 2-man aircraft.〔(Hyfish Fuel Cell ) Treehugger News〕
==General History==
The Hyfish is a product of the German Air & Spacecenter and its international partners.〔Howard, Courtney E. "Hydrogen Fuel-Cell Technology Takes Off, Powering Hyfish UAV. (Cover Story)." Military & Aerospace Electronics 18.6 (2007): 1-14.〕 The German Air & Spacecenter, otherwise known as the Deutsches Zentrumfuer Luft-und Raumfahrt, or DRL, is located in Stuttgart, Germany.〔Howard, Courtney E. "Hydrogen Fuel-Cell Technology Takes Off, Powering Hyfish UAV. (Cover Story)." Military & Aerospace Electronics 18.6 (2007): 1-14.〕 These partners included, but were not limited to, Horizon Fuel Cell Technologies of Singapore. Development of the Hyfish, an unmanned aerial vehicle that is jet powered by hydrogen fuel cell technology, took eighteen months of hard-work and laboring research.〔Howard, Courtney E. "Hydrogen Fuel-Cell Technology Takes Off, Powering Hyfish UAV. (Cover Story)." Military & Aerospace Electronics 18.6 (2007): 1-14.〕 Unmanned aerial vehicles are also called UAVs. UAVs are difficult to power because they have to be small and light in order to be able to maintain flight in the air. To resolve this challenge, Scientists at the DLR Institute for Technical Thermodynamics in Stuttgart integrated Horizon Fuel Cell Technology’s fuel cell system into the Hyfish.〔Howard, Courtney E. "Hydrogen Fuel-Cell Technology Takes Off, Powering Hyfish UAV. (Cover Story)." Military & Aerospace Electronics 18.6 (2007): 1-14.〕 In order to prepare the Hyfish for flight, the SmartFish team had to test the CFD of the aircraft numerous times.〔"HyFish." Smartfish. Team Smartfish GmbH, 2003. ().〕 The most influential reasoning behind the creation of the Hyfish was to demonstrate and test the effectiveness of fuel cells in a challenging environment, which in this case, involved flight in the air.〔"HyFish." Smartfish. Team Smartfish GmbH, 2003. ().〕 However, the construction of the Hyfish also helped researchers educate themselves more in the subject of lightweight construction in addition to the subject of the packaging of fuel cell systems.〔"HyFish." Smartfish. Team Smartfish GmbH, 2003. ().〕 This unmanned UAV took its first flight in 2007. Bern, Switzerland is able to claim this historical event.〔Howard, Courtney E. "Hydrogen Fuel-Cell Technology Takes Off, Powering Hyfish UAV. (Cover Story)." Military & Aerospace Electronics 18.6 (2007): 1-14.〕 The Hyfish was put on display at the Hannover fair, otherwise known in Germany as the Hannover Messe, for spectators. This event lasted April 16–20, 2007.〔"HyFish: A Hydrogen Fuel Cell Powered UAV." Tech Industry News, 16 Apr. 2007. ().〕
