Abstract
To evaluate these materials as cathode materials for solid oxide fuel cells (SOFCs), the chemical compatibility of LnSF with yttria-stabilized zirconia (YSZ) was investigated. Despite significant differences in ionic and electronic conductivity, the performance of the symmetric cells with composite cathodes formed by infiltration of doped LnFeO3 into YSZ and calcination to 1123 K were essentially independent of the transport properties of the cathode materials, exhibiting an identical impedance of 0.08 Ω∙cm2 at 973 K.
Microsoft is Ending Support for Windows 7
