ABSTRACT:
Perovskite oxides of La0.6Sr0.4Co0.3Fe0.8O3, (LSCF) were synthesized as a new cathode material for intermediate temperature – solid oxide fuel cell (IT-SOFC) by gel-combustion method. Nitrates of La, Sr, Co and Fe were used as precursor and citric acid as self combustion reaction matter. The as-prepared cathode material was characterized for BET surface area, X-rays diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermal analysis, and conductivity. Electrochemical impedance was measured at different temperatures by sintering the LSCF pellets at 900 °C for 2 h. The conductivity measurement showed the highest value as 0.89 S cm-1 at 700 °C. The result shows that the LSCF can efficiently work as an intermediate temperature cathode material for solid oxide fuel cells.
