Electrochemical performance of (Bi2O3)1-z(Er2O3)z-Ag composite material for intermediate temperature solid ozide fuel cell cathode

摘要：

The electrochemical performance of ESB (Bi2O3)1-x (Er2O3) x-Ag composite material for IT-SOFC cathode was studied on the SSZ (ZrO2).89(Sc2O3)0.1(CeO2)0.01 electrolyte. The influence of different ESB/Ag ratio and erbium-doped content on the performance of the composite cathode was investigated using AC impedance spectroscopy analysis. The investigation showed that there was a low polarization resistance (0.16Ω cm2 to 0.50 Ω cm2 at temperatures from 750℃ to 650℃) when the content of 3ESB (Bi2O3)0.7(Er2O3)0.3 and Ag was equal in composite cathode.
