Abstract
The electrochemical performance of ESB [(Bi2O3)1 − x(Er2O3) x]–Ag composite material for IT-SOFC cathode was studied on the SSZ [(ZrO2)0.89(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 (0.16 Ω cm2 to 0.50 Ω cm2 at temperatures from 750 °C to 650 °C) when the content of 3ESB [(Bi2O3)0.7(Er2O3)0.3] and Ag was equal in composite cathode.
