DLR

The German Aerospace Center (DLR) is Germany’s research centre for aeronautics and space. It is the largest engineering research organization in Germany undertaking applied research and development in Aeronautics, Space, Energy, Transport and Security. Approximately 7700 people are employed at 16 locations in Germany. Research at the Institute of Technical Thermodynamics in Stuttgart concentrates on efficient and resource-saving energy storage and conversion technologies.

It ranges all the way from theoretical studies and basic laboratory research to the operation of pilot installations, complemented by analytical system studies. The use of fuel cells is considered in many areas, ranging from stationary energy supply to mobile applications. The institute develops and investigates solid oxide fuel and electrolyzer cells (SOFC/SOEC) for many years. The research activities comprise fabrication technologies for advanced cell concepts (metal-supported SOFC), cell and stack design, in-situ and ex-situ analytics with innovative measuring techniques, such as spatially resolved methods, as well as system optimization and demonstration.

Within ENDURANCE, DLR carries out short-stack and stack tests through sophisticated analytical methods such as spatially resolved measuring techniques with segmented cell technology, contact resistance measurements and electrochemical impedance spectroscopy (EIS). These investigations provide detailed results on degradation processes and mechanisms at cell/interconnect and cell/seal interfaces as well as on cell and stack level, which are necessary for the development of accelerated lifetime tests, vital to the project aims.
