Solid oxide fuel cell (SOFC) is very popular nowadays because of its high efficiency, fuel flexibility, long-lasting and eco-friendly energy conversion device. Till date, yttria stabilized zirconia (YSZ) system has been dominated in the SOFC world in which Ni/YSZ cermet is commonly used as anode material. But Ni/YSZ cermet anodes shows, carbon deposition and rapid performance degradation when hydrocarbon fuels are used. Alternative perovskite systems La<SUB>1-x</SUB>Sr<SUB>x</SUB>Cr<SUB>1-y</SUB>M<SUB>y</SUB>O<SUB>3-δ</SUB> (M: Mn, Fe, and V) have attracted much attention as anode material due to their high-temperature stability, low carbon deposition, and high catalytic activity. In the present work, La<SUB>0.75</SUB>Sr<SUB>0.25</SUB>Cr<SUB>0.5</SUB>Mn<SUB>0.5</SUB>O<SUB>3-δ</SUB> (LSCM) is synthesized by solid state synthesis method. Compatibility of the anode material with perovskite electrolyte (La<SUB>1-x</SUB>Sr<SUB>x</SUB>Ga<SUB>1-y</SUB>Mg<SUB>y</SUB>O<SUB>3-δ</SUB> ) is evaluated by XRD analysis, SEM, impedance spectroscopy and 4-probe method. Using an organic solvent-based formulation, flexible and homogeneous LSCM tapes were cast for potential use as an anode in SOFC.
