The Preparation and Characterization of LSCF and LCCF Perovskite Cathode Electrode for Solid Oxide Fuel Cell Applications

In this paper, LaSrCoFe and LaCaCoFe powders compositions were prepared with the solid state reaction. The crystal structure of powders perovskite possess hexagonal type crystal lattice according to the literature survey. Crystallographic and micro structural properties of the produced powder were characterized by XRD.   Lattice parameter for LSCF a=5.471 Å,c=13.47 Å and for LCCF a=5.435 Å, c=13.23 Å. Cathode electrode which is small crystal particle was formed into a thin film. The conductivity of the thin film LSCF was measured by four probe conductive.
