dc.description.abstract | In this study A-site deficient lanthanum doped strontium titanate, which is considered as a promising, redox-stable candidate for full ceramic anodes in Solid Oxide Fuel Cells (SOFCs), was produced by nanoparticle-based spray pyrolysis. In this process cost-effective nitrate salts and titania nanoparticles are used as precursors. LST with a nominal composition of La_0.2Sr_0.7TiO3 showed limited stability at temperatures higher than 1290°C. It was observed that minor contents of secondary phases, which form at elevated temperatures, invoke a drastic loss of the electrical performance. Thermal stability is significantly increased by a slight enrichment of strontium. The phase pure A-site deficient LST shows remarkably higher electrical performance than similar stoichiometric counterparts. Reductive sintering results in a conductivity as high as 600 S cm−1 at 600°C. Furthermore the A-site deficient LST shows a high redox-stability and fast redox-kinetics. With these properties LST is a suitable material for the fabrication of a new generation of Ni-free ceramic SOFC anodes. Secondary phases have a significant influence on the electrical conductivity and redox behaviour. | de_CH |
