| Abstract: Transition metal (Mn, Fe, Co, Ni, Cu) oxide was formed in LSM-YSZ cathode by nitrate solution infiltration method. LSM-YSZ/YSZ/LSM-YSZ symmetric cell performance at intermediate temperature range 600～800 ℃ was studied by electrochemical impedance spectroscopy (EIS). EIS test results showed that the polarization resistances of LSM-YSZ with metal oxide infiltration were much lower than that without metal oxide infiltration, 60%～80% polarization resistance decrease was reached by metal nitrate solution infiltration. The activation energy of oxygen reduction reaction derived from polarization resistance showed that the performance of LSM-YSZ with different metal oxide infiltration has different activation energy decrease, Co nitrate infiltration showed the biggest activation energy decrease. Mn, Fe and Cu nitrate solution infiltrated LSM-YSZ showed good polarization resistance decrease at the tested temperature range. |
