Abstract

In this study, samarium strontium cobaltite, Sm0.5Sr0.5CoO3−δ (SSC) and samarium doped ceria, Sm0.2 Ce0.8O1.9 (SDC) carbonate or (SDCC) was used as the new composite cathode powder materials. This composite cathode powder was prepared via high energy ball milling (HEBM) technique for LTSOFC application. Various weight percentages of SDCC ranging from 50 wt% to 70 wt% was chosen to be added with SSC powder. The prepared samples of SSC–CE55, SSC-CE64 and SSC-CE73 composite cathode powders were characterized by using TGA, XRD, FTIR in order to investigate their physical structural, morphological and chemical compatibility. Result shows that this new composite cathode powders obtained good thermal stability, chemical compatibility and exhibit no trace of dissimilar phase from both SSC and SDCC. The existence of carbonates layer in the SSC-SDCC composite cathodes powder has been verified by analysis of the FTIR spectra.
