【Abstract】 The Bi₂VO_5.5 is a kind of ideal electrolyte materials in oxygen generator at the middle low temperature because it has high oxygen ion conductivity at low temperature. The double doped Bi₂V_0.9Cu_0.075Nb_0.025O_11-δ electrolyte ceramic membrane with the highest oxygen ion conductivity is optimized, and the mechanical properties are improved. The electrolyte powders synthesized by co-precipitated method can improve the properties of the electrolyte membrane. The mixed oxides of La_0.6Sr_0.4Co_0.8Fe_0.2O₃ and Bi₂Cu_0.1V_0.9O_5.35 is optimal electrode materials of BIMEVOX electrolyte ceramic membrane. In this paper, the effect of double-doped metal ion, synthesis method and electrode material on the properties of BIMEVOX electrolyte ceramic membrane is reviewed.更多还原
