Synthesis and characterization of terbium doped barium cerates as a proton conducting SOFC electrolyte

A novel proton conductor, BaCe0.95Tb0.05O3� a (BCTb) perovskite was synthesized via the EDTA-citrate acid complexing method, followed by high temperature calcination. The properties of the powders were characterized by thermo gravimetric-differential thermal analysis (TG-DTA), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and the conductivity measurement using the 4-probe method. In order to obtain the pure perovskite structure, the calcination temperature was elevated at 1000 � C or greater. The elec
