Electrical Conductivity and Characterization of CeO2 Doped 8YSZ Electrolyte with 2%wt CuO Doping
Nano-sized electrolyte of CeO2 doped 8YSZ with 2%mol CuO (YSZDC) powders were synthesized by solid-state reaction method.Powder characteristics and electrical properties was characterized by XRD,SEM and Electrochemical workstation.The results demonstrate that the as-synthesized Y0.08Zr0.72Ce0.2O1.6 (YSZDC) and Y0.08Zr0.72Ce0.2O1.6-CuO0.02 (YSZDC-Cu0.02) possessed similar powder characteristics,including cubic fluorite crystalline structure.About 150 ℃ reduction in densification temperature of Y0.08Zr0.72Ce0.2O1.6-CuO0.02 was obtained when compared with Y0.08Zr0.72Ce0.2O1.6.The YSZDC-Cu0.02 pellets sintered at 1300℃ and the YSZDC sintered at 1450℃ exhibited relative densities of 95.66% and 94.73%,respectively.Electrolyte were prepared for electrolyte-supported SOFCs (ES-SOFC),the suspension of NiO-YSZ anode was sprayed on the electrolyte,after co-sintering at 1300℃,electrolyte and anode were well adhered each other,without connecting pores and cracks observed.Moreover,well electricity performance were showed by YSZDC and YSZDC-Cu0.02 at a testing temperature of 750℃,and the electrolyte conductivity didnt decrease obviously with doping CuO.
