Preparation, Characterization and Intermediate-Temperature Electrochemical Properties of Er(3+)-Doped Barium Cerate–Sulphate Composite Electrolyte

In this study, BaCe(0.9)Er(0.1)O(3−α) was synthesized by a microemulsion method. Then, a BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) composite electrolyte was obtained by compounding it with a K(2)SO(4)–Li(2)SO(4) solid solution. BaCe(0.9)Er(0.1)O(3−α) and BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) were...

description In this study, BaCe(0.9)Er(0.1)O(3−α) was synthesized by a microemulsion method. Then, a BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) composite electrolyte was obtained by compounding it with a K(2)SO(4)–Li(2)SO(4) solid solution. BaCe(0.9)Er(0.1)O(3−α) and BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectrometry. AC impedance spectroscopy was measured in a nitrogen atmosphere at 400–700 °C. The logσ~log (p(O(2))) curves and fuel cell performances of BaCe(0.9)Er(0.1)O(3−α) and BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) were tested at 700 °C. The maximum output power density of BaCe(0.9)Er(0.1)O(3−α)–K(2)SO(4)–BaSO(4) was 115.9 mW·cm(−2) at 700 °C, which is ten times higher than that of BaCe(0.9)Er(0.1)O(3−α).
