摘要:
Abstract: Perovskite Ba0.8La0.2FeO3-δ was synthesized via a glycine–nitrate process as the cathode material for intermediate-temperature solid oxide fuel cells. Ultra-fine pure phase Ba0.8La0.2FeO3-δ powder was obtained after the self-propagating combustion of a complex xerogel precursor. The Ba0.8La0.2FeO3-δ cathode showed good compatibility and an enhanced phase interface with a samarium-doped ceria electrolyte. Electrochemical measurements showed that the Ba0.8La0.2FeO3-δ cathode achieved a low polarization resistance of 0.58 Ω cm2 at ...
