Abstract

The effects of calcination factors on the La0.6Sr0.4Co0.2Fe0.8O3-δ-SDCC (LSCF-SDCC) composite cathodes powder were investigated. LSCF-SDCC has been prepared using high energy ball milling technique via dry milling method. The resultant LSCF-SDCC composite cathodes powder then were calcined at 700, 750 and 800 °C with soaking time of 1, 2 and 3 hours. The findings reveal that different calcinations temperature and soaking time gives effects to the composite cathodes powder. Clear peak intensity demonstrate from calcination temperature 750 °C as confirm via XRD analysis indicates that crystalline structure has been improved. FESEM investigation demonstrate the presence of large particles in the resultant powder resulting from the increased calcination temperature and soaking time. LSCF-SDCC composite cathodes powder calcined at a temperature of 750oC for soaking time 1, 2 and 3 hours demonstrates good crystallite structure to be served as composite cathode SOFCs compared to samples calcined at 700oC and 800oC with soaking time 1, 2 and 3 hours.
