چكيده فارسي :
Nano-sized cobalt oxide decorated La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode was investigated as a
promising cathode for intermediate temperature solid oxide fuel cells (IT-SOFC). To characterize
the polarization resistance (Rp) of the infiltrated and non-infiltrated cathodes, an equivalent
circuit was fitted onto the electrochemical impedance spectroscopy (EIS) data. Compared to pure
LSCF, the high frequency polarization resistance decreased significantly as much as 87% at 600
°C by presence of cobalt oxide nano-particles.
