Modified Pechini synthesis and characterization of Y-doped strontium titanate perovskite

This work reports the modified Pechini preparation and properties of an A-site deficient perovskite Sr0.86Y0.08TiO3−δ (SYT). Good chemical homogeneity and electrical conductivity were determined, making SYT a potential conductive component material in a composite anode for solid oxide fuel cells. As an oxide with inherent resistance to oxidation and hydroxylation, SYT could be a substitute for the metallic Ni component in composite anodes for solid oxide fuel cells, particularly for reversible solid oxide fuel cells with attendant high steam concentrations.
