High temperature Raman spectroscopy of Sm doped CeO 2 /carbonate composite was measured in order to discuss the interaction between carbonate ion and solid oxide electrolyte at an interface LT-SOFC. In spectra with breathing mode NK initial heating process, whereas separated ν 1 (CO 3 2- ) bands assigned Na CO K are observed clearly lower temperature, unifying these due state migration carbonates than eutectic point (983 K). Degree is affected by apparent average thickness (AAT) amount oxide. Solid diffusion mixture assisted coexistence oxides.
