Influence of Thickness on Oxide Ionic Conductivity in Sm3+ and Nd3+ Co-Doped CeO2 Electrolyte

摘要：

　　Sm3+ and Nd3+ co-doped CeO2 solid electrolytes with various thicknesses were prepared by citric-nitrate combustion process.The electrical conductivity as a function of electrolyte thickness was determined by ac impedance spectroscopy.The results showed that the ionic conductivity increases with the decrease of the electrolyte thickness approximately and it was estimated that the conductivity enhancement was due to the increased grain boundary conductivity.
