The ABO3 perovskite structure system Sr doped LaMnO3 has high electrical conductivity at solid oxide fuel cell (SOFC) operating temperatures (600&sim;1000°C), whereas Sr doped LaFeO 3 materials possess better thermal expansion coefficient matching with yttria stabilized zirconia electrolytes for SOFCs.

520 $a The ABO3 perovskite structure system Sr doped LaMnO3 has high electrical conductivity at solid oxide fuel cell (SOFC) operating temperatures (600&sim;1000°C), whereas Sr doped LaFeO 3 materials possess better thermal expansion coefficient matching with yttria stabilized zirconia electrolytes for SOFCs.
520 $a In this work, systematic studies were performed on two new series of materials Fe doped (0, 5, 10, 15, 20, 25 mol %) La0.84 Sr0.16MnO(3 - delta) and Mn doped (0, 5, 10, 15, 20, 25 mol %) La 0.84Sr0.16FeO(3 - delta) in order to examine the effect of powder morphology, densification, electrical conductivity at elevated temperatures under various atmospheres (air, Ar, N2, 5%H2 + Ar). The extra progress was carried out with in-house produced powder synthesized by citric-gel auto ignition process (CGP).
520 $a It is found that all compositions produced by the CGP process were of ABO3 perovskite structure. The highest sintered density obtained for both systems was over 98% of theoretical density. The electrical conductivity for both systems is strongly affected by the dopant (Mn or Fe) concentration, operating temperature, and atmosphere. (Abstract shortened by UMI.)
