제목 Effects of zinc nitrate as a sintering aid on the electrochemical characteristics of Effects of zinc nitrate as a sintering aid on the electrochemical characteristics of Sr0.92Y0.08TiO3-δ, and Sr0.92Y0.08Ti0.6Fe0.4O3-δ anodes 
초록 Although Sr0.92Y0.08TiO3-δ (SYT) and Sr0.92Y0.08Ti0.6Fe0.4O3-δ (SYTF) have been widely considered as promising materials for solid oxide fuel cell anodes, the poor densification restricts their commercial applications. As a sintering aid, zinc nitrate successfully stimulates the sintering process and improves densification. A linear shrinkage investigation and scanning electron microscopy images have indicated that the sinterability of SYT and SYTF materials is effectively improved by impregnating the green body with 5 mol% Zn. Zinc modification lowers the activation energy of the electrical conduction process and significantly improves the electrical conductivities of SYT and SYTF at all atmospheric conditions.
