摘要：
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 d-phase with cubic fluorite structure. The conductivity of (YO1.5)(0.2)(MoO3)(0.05)(ErO1.5)(0.05)(BiO1.5)(0.7)ceramic electrolyte sintered at 925? for 10 h reached 12.26 x 10(-2) S cm-1 at 700?. It has good thermal stability and is a promising electrolyte material for SOFC.
