Abstract
The correlation of cathode microstructure with the electrochemical behavior of LSCF-SDCC has been studied. In this study, LSCF-SDCC composite cathode powders were hamimah@uthm.edu.my prepared using ball milling and calcined at 700-900°C. Cathode pellets were fabricated using the calcined powders via uniaxial press and sintered at 600°C. A reduction of pellet porosity (33.1-29.8%) was observed as the calcination temperature increased, which was also in line with the cross-sectional view of the pellet. In electrochemical analysis, dominant resistance was observed in all samples which corresponded to low adsorption of oxygen. Meanwhile, cathode prepared with calcined powders of7 50°C exhibited the least area specific resistance that yielded single cell performance of 139m W/cm 2 at 550°C.
