Fabrication and Properties of Ba(Zr0.63Ce0.27)Y0.1O3-δ/ZnO Electrolyte Materials

摘要：

　　The perovskite-type Ba(Zr0.63Ce0.27)Y0.1O3-δ (BZCY) was synthesized by solid-state reaction.Sintering behavior and electrical conductivity of the electrolyte materials were improved through optimizing the content of ZnO sintering aid.The significant enhancement of density of sintered body was observed.Relative densities of the samples increased with ZnO content added.A conductivity of 9.27×10-3 S/cm tested in humid hydrogen at 800℃ was obtained when the ZnO content was 2 mol%.A peak power density of 12.4 mW/cm2 was delivered based on a single fuel cell with electrolyte-supported configuration.
