Doped ceria has emerged as a promising material for Solid Oxide Fuel Cells (SOFCs) due to its high oxygen ion conductivity. In this study, we delve into the intricacies of doped ceria's behavior by combining Micro Raman and impedance spectroscopy measurements. Our investigation uncovers a lower activation energy to ionic conductivity above 750 K, coinciding with a notable discontinuity in the Raman shift of the CeO₂ signal at the same temperature. This correlation provides valuable insights into the underlying mechanisms governing the enhanced ionic conductivity in doped ceria. Solid Oxide Fuel Cells (SOFCs) have garnered significant attention as clean and efficient energy conversion devices. Doped ceria, a derivative of cerium oxide (CeO₂), has emerged as a leading candidate for electrolyte materials in SOFCs due to its high oxygen ion conductivity. To elucidate the temperature-dependent behavior of doped ceria, we employed Micro Raman and impedance spectroscopy techniques.
