Bismuth oxide-based electrolyte materials co-doped with yttrium and erbium were synthesized by nitrate combustion method. The crystal structure was analyzed by X-ray diffraction. The data on electrical conductivity were carried out using AC impedance spectroscopy. The results suggested that all of the co-doped bismuth oxide samples obtained δ-phase with cubic fluorite structure. The conductivity of (YO1.5)0.2(MoO3)0.05(ErO1.5)0.05(BiO1.5)0.7ceramic electrolyte sintered at 925∘C for 10 h reached 12.26 × 10−2S cm−1at 700∘C. It has good thermal stability and is a promising electrolyte material for SOFC.
