Investigation of samarium and neodymium co-doped BaCeO3 electrolyte for proton-conducting solid oxide fuel cells
BaCe0.8Sm0.2-xNdxO3-δ (x = 0, 0.05, 0.1, 0.15) powder was prepared using the glycine-nitrate combustion method, its crystal structure, microscopic morphology and electrochemical properties were investigated. X-ray diffraction analysis showed that the BaCe0.8Sm0.2-xNdxO3-δ powder with orthorhombic perovskite structure could be obtained after calcined at 1150 °C. Scanning electron microscopy showed that BaCe0.8Sm0.2-xNdxO3-δ sintered samples exhibited a dense structure. Electrochemical impedance tests showed that the substitution of Nd3+ improved the electrical conductivity of the BaCeO3-based electrolyte materials. The proton conductivity of BaCe0.8Sm0.15Nd0.05O3-δ samples reaches a maximum value of 0.035 S cm−1 in a wet air environment at 700 °C.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
