For example, a PEM fuel cell system including tank has a much higher specific energy density (400Wh\/kg @350Bar) than conventional Li-ion batteries (150 Wh\/kg), whereas Li-ion batteries have a higher specific power density.<\/p>\n\n\n\n<p>The advantage of a higher specific energy density allows higher ranges in the automotive sector and, as here in the case of a UAS, longer flight times. For example, theory and even initial projects have shown that fuel cell-powered UAS are capable of hovering (&#8222;hovering&#8220;) for more than 3h, whereas most battery-powered UAS do not exceed 30-40min flight time.<\/p>\n\n\n\n<p>Thus, a PEM fuel cell system lends itself to UAS applications that do not require a high payload (&#8222;payload&#8220;) or fast flights, where a higher specific power density would be needed, but for long flight times with as stationary flight behavior as possible.<\/p>\n\n\n\n<p>This is an internal research project of the Chair of Control Engineering at HSU. In this project, a fuel cell-powered UAS is to be built, tested and optimized. Subsequently, possible future applications will be derived and the UAS will be adapted accordingly. Applications as a so-called &#8218;flying eye&#8216; in the field of hazard, accident, fire or traffic monitoring using a suitable camera system, which sends a video stream in real time to a ground station, would be conceivable.<\/p>\n\n\n\n<p>If you would like to be part of this exciting development process or learn more about this project, feel free to contact <a href=\"https:\/\/www.hsu-hh.de\/rt\/team\/m-sc-andreas-cloppenborg\">Andreas Cloppenborg<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The &#8218;PEM Fuel Cell Powered UAS&#8216; project is investigating the advantages and feasibility of a PEM fuel cell powered Unmanned Aerial System (UAS) and applications to be derived from it.
