Padigela SrinivasReddy, Prashanth Kumar Vaidya and Suresh Sripadad
Abstract
Growth of new practical materials with enhanced characteristics for solid oxide fuel cells (SOFCs) are
one of the main criteria of modern science and materials science. Elevated electro catalytic behavior in
oxygen reduction reaction cases, The most essential requirements for cathode materials used in SOFCs
are chemical and thermo mechanical compatibility with solid electrolytes, as well as stability at elevated
temperatures. The data available in the literature on crystal structure, temperature, electro transportrelated, and other functional aspects of these materials are summarized in this review. The focus here is
on cutting-edge ways to enhancing the functional properties of these complex oxides. Here we started
synthesis with Sol-Gel method of the Sm0.8 Sr0.2 Fe1-x Cox O3 (at x = 0, 0.2, 0.4) and the structural analysis
are done with XRD, morphological approach was done with FESEM and TEM, the weight loss of the
compositions was characterized with Thermo Gravimetric method and the electrical properties are
carried out using four-probe technique of temperature to nearly 600o
C and the conductivity calculated
as nearly 125.87 S/cm to 881 S/cm which are highly useful for the fabrication of SOFCs as a cathode
materials which are exhibits O-type (a < c/√2 < b) structural character
