000885983 520__ $$aDevelopment of solid oxide cells (SOC) over several decades has led to substantial enhancement of the cell performance and a profound understanding of degradation mechanisms. Moving past the basic limitations caused by design, processing and microstructural issues, it becomes clear that further progress requires application-oriented research activities and cell designs. The optimum material combinations and microstructure of a cell is likely to differ depending on operational mode, intended operation temperature and lifetime as well as between stationary and mobile application. According to these boundary conditions, various research topics have been tackled at Forschungszentrum Jülich. On the basis of the well-known anode-supported cell (ASC) concept, electrode development and optimization of the electrolyte layer was performed aiming at low-temperature operation (<600°C). By implementation of a GDC electrolyte, for example, the ohmic resistance was reduced by more thana factor of 3. Investigation of highly active Ni/GDC cermets as fuel electrode are another topic of investigation. First progress achieved on metal-supported cells can be transferred for ongoing work to further increase low-temperature performance of ASCs. The material development is aided by electrochemical testing of symmetrical cells and full-cells and supported by theoretical considerations of the materials elementary properties.
