Enhanced ionic conductivity of co-doped ceria-carbonate nano composite electrolyte material for LT-SOFCs
Abstract
Co-doped ceria Ce0.8Sm0.1Y0.12-δ and co-doped ceria-carbonate nano composite Ce0.8Sm0.1Y0.1O2-δ – (Na-K)2CO3 used as electrolytes in low temperature solid oxide fuel cells (LT-SOFCs) were synthesized. Structural and morphological studies were characterized by XRD and SEM. Electrical conductivity measurements were carried out by using Impedance Spectroscopy in the temperature range of 100 to 500°C. It was observed that the co-doped ceria-carbonate Nano composite material exhibited high ionic conductivity than that of co-doped ceria making it useful as promising electrolyte material for LT-SOFCs.
