Abstract
The monoclinic Bi-Sr-Co-O compound was successfully synthesized by ethylene glycol-citrate acid polymerization method. The prepared sample was evaluated by various experimental tests. Powder X-ray diffraction (XRD) data shows the Bi-Sr-Co-O powder with good crystallinity. Its good thermal stability and chemical compatibility with Ce0.9Gd0.1O2− γ electrolyte was also proved by XRD data. The chemical composition of Bi-Sr-Co-O powder was confirmed by ICP-AES and XPS analysis. The compatibility with the electrolyte, along with the encouraging electrical conductivity (around 10 S·cm−1 in the temperature range of 600-700 °C), allows us to conduct further study on Bi-Sr-Co-O as a potential novel cathode material for intermediate temperature-solid oxide fuel cells.
