AuRora - Self-sustaining reversible solid oxide cell (SOFC/SOEC) propulsion system for a self-launching glider

Within this project, an electric propulsion system for a self-launching glider is investigated based on a high temperature solid oxide cell. This solid oxide cell (SOFC/SOEC) is to be operated in flight in the fuel cell mode and on the ground, with additional supply of electricity and water, in the electrolysis mode in order to produce hydrogen. With that alternative fuel a self-sufficient operation of the entire propulsion system is guaranteed. Compared to thermal engines the solid oxide fuel cell has a much greater efficiency, lower emissions and has similar power densities as battery powered propulsion systems. The independent propulsion system will be validated as a scaled model in the reversible mode experimentally.
