Preparation of dense and uniform La0.6Sr0.4Co0.2Fe0.8O3− (LSCF) films for fundamental studies of SOFC cathodes

Chemical and structural stability of La0.6Sr0.4Co0.2Fe0.8O3− ceramic vs. medium/high water vapor pressure

“…A small broad band at 180 cm À 1 is also detected. The first two bands at 662 and 569 cm À 1 are similar to those observed in the literature [18,[39][40][41][42]. It should be noted that according to its complex composition, LSCF6428 can be considered as a solid solution between La 1 À x Sr x CoO 3 À δ (LSC) and La 1 À x Sr x FeO 3 À δ (LSF).…”

Copper oxide as a synergistic catalyst for the oxygen reduction reaction on La0.6Sr0.4Co0.2Fe0.8O3−δ perovskite structured electrocatalyst

“…But it is much lower than those reported for doped ceria, which are known to be excellent ionic conductor and improve the ORR through extending the three-phase boundary length. According to the model suggested by Maier et al [33,34] and Liu et al [35] for the LSCF electrodes, the high frequency feature can be assigned to the oxygen ion transfer across the interface between the cathode and the electrolyte, while the low frequency feature can be assigned to the electrochemical oxygen surface exchange reaction. Combined with the result in ECR experiment, CuO displays significant synergistic ORR catalytic activity on the LSCF surface.…”

Preparation and Characterization of (La0.8Sr0.2)0.95MnO3−δ (LSM) Thin Films and LSM/LSCF Interface for Solid Oxide Fuel Cells

“…Another limitation of LSCF cathode for the performance maximization is its surface catalytic activity. The electrochemical activity of the stand‐alone LSCF cathode is likely to be limited by the surface catalytic properties . On the other hand, LSM cathode is known to have strong oxygen adsorption characteristics with rapid catalytic kinetics as well as higher chemical stability, which can help overcome the electrochemical and chemical limitation of the LSCF cathode.…”
