Outline of Final Research Achievements

In the present study, the performance enhancement mechanism of LSCF-GDC composite cathode of SOFC is investigated. Cathodes with different LSCF-GDC volume fractions are fabricated, and their polarization characteristics and 3D micro structure parameters are measured. It is found that three phase boundary reaction must be considered in order to quantitatively reproduce the experimental trend.
