ABSTRACT:
Nickel containing and cobalt free Perovskite oxides of Ba0.2 Sr0.8 Ni0.8 Fe0.2 O3-d (BSNF) were synthesized as a new cathode material for intermediate temperature – solid oxide fuel cell (IT-SOFC) by glycine nitrate process (GNP). Nitrates of Ba, Sr, Ni and Fe were used as precursor and glycine as self combustion reaction matter. Electrochemical impedance, conductivity, X-rays diffraction (XRD), and scanning electron microscopy (SEM) measurements were carried out of newly synthesized BSNF cathode material. Electrochemical impedance was measured at different temperatures by sintering the BSNF pellets at 900°C for 2 h. The conductivity measurement showed the highest value as 0.081 S cm-1 at 650°C. Temperature dependence area specific resistance (ASR) of BSNF cathode material was also calculated and the minimum ASR value measured was 0.783 O cm2 at 650°C. The results shows that BSNF can work as a good alternative of cobalt free, low-cost and intermediate temperature cathode material for solid oxide fuel cell.
