To study the single and multiple impurities poisoning phenomena in the SOFC cathode systems, three common cathode materials, LSM, LSCF, and LNO, were prepared, sintered, and annealed at various temperatures with different impurity-containing atmospheres, respectively. Through X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Transmission electron microscopy (TEM) technique, as well as the CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) methodology, the secondary phases under different conditions (temperatures and the partial pressure of oxygen and impurities) were predicted and experimentally verified correspondingly. Furthermore, comprehensive comparisons among the three candidates under different impurity-containing conditions were also made to recommend promising cathode materials.
