Abstract

Abstract: A series of solid state electrolytes, Ce_5.2RE_0.8MoO_15-δ(RE=Y, La, Sm, Gd, Dy, Ho, Er), were synthesized by sol-gel method. Their structures and electrical conductivities were characterized by X-ray Diffraction(XRD), Raman and X-ray Photoelectron Spectroscopy(XPS) and AC impedance spectroscopy, respectively. The results show that the concentrations of oxygen vacancy increased with increasing x and their conductivity were improved. And the cell parameters increase as the radius of RE³⁺ increases. Because the ionic radius of doped Dy³⁺(0.0908 nm) is closed to that of Ce⁴⁺(0.0920 nm), their oxide has minimal cell elastic straining between RE³⁺and oxygen vacancy, and the system has the least association enthalpy, thus the oxide Ce_5.2RE_0.8MoO_15-δ exhibits a higher conductivity(7.02×10^-3 S/cm) and lower activation energy(1.056 eV) compared to the other doped compounds.

Key words: Solid state electrolyte, Conductivity, Sol-gel method, SOFCs
