Investigation of Cathode/Electrolyte Interfaces in Solid Oxide Fuel Cells by using FIB-STEM Techniques
MetadataShow full item record
The evolution of cathode/electrolyte interface in solid oxide fuel cells (SOFCs) during operation is an important indicator for evaluating the overall performance of a cell. In this thesis, the most important and typical interfaces were studied in great details under wide range of SOFC operation conditions using combined focused ion beam-scanning transmission electron microscopy techniques. The results clearly demonstrate the dynamic relationship between interface, segregation, and performance of cathode materials for fuel cells.
