Resumo
The (La0.60Sr0.40)(Co0.20Fe0.80)O3-δ - LSCF, (Ce0.90Gd0.10)O1.95 - CGO composites and
LSCF were deposited by wet powder spraying deposition method for the purpose of investigating
their potential use in Intermediate Temperature Solid Oxide Fuel Cells. The interlayers are
necessary between CGO electrolytes and LSCF cathodes in order to improve the performance of
these materials. LSCF powders synthesized by citrate technique were calcined at 900 °C for 4 h
and, their LSCFCGO composites and LSCF suspensions deposited on CGO substrate and, sintered
in 1100 °C for 1 h, were formed pseudo-perovskite. The ceramics materials were analyzed by X-ray
diffraction (XRD) and chemical composition of different half-cells layers by scanning electron
microscope with energy dispersive (SEM-EDS). The results are in agreement with the literature and
indicate that route studied is adequate for crystal structures formation compatible with films the 35
µm thick total for study of conductivity between the cathode and the electrolyte.
