La0.25Sr0.25Ca0.40Ti0.95Ni0.05-xSnxO3-?(x=0...0.05) mixed ionic electronic conductor (MIEC) materials were studied as possible fuel electrodes for solid oxide cell. Initial characterization of the materials aimed to understand whether tin occupied the A- or the B-site in the material through precise control of material stoichiometry using thermogravimetric analysis (TGA) and XRD characterization. Thereafter, a set of La0.25Sr0.25Ca0.40Ti0.95Ni0.05-xSnxO3-?materials were synthesized and characterized to understand the influence of the B-site dopant on the phase purity and time-stability in reducing atmosphere. Finally, initial electrochemical characterization has been conducted for some of the synthesized materials. |
