Preparation and properties of yttrium-doped SrTiO3 anode materials
Source abstract
Abstract
Abstract Direct electrochemical oxidation of hydrocarbon fuels is a current development trend of solid oxide fuel cells (SOFCs) and finding new anode materials for this application is a key issue. In this study, promising candidates, Y 2 O 3 -doped SrTiO 3 perovskite compounds Sr 1−1.5 x Y x TiO 3 ( x = 0.02, 0.04, 0.06, 0.08, 0.10), were synthesized by solid-state reaction. The structure of the calcined powders was examined by X-ray diffraction (XRD). The sinterability and high temperature conductivity were measured by the Archimedes principle and a dc four-probe method, respectively. The effect of sintering temperature on the electrical conductivity was studied. The results indicated that the optimal sintering temperature is around 1400 °C. From 400 °C to 1000 °C, the conductivity decreased with increasing temperature. At 800 °C the highest conductivity (26.8 S/cm) was observed for x = 0.08.
