Abstract
IT-SOFC cathode materials such as the double perovskite SmBa0.6Sr0.4Co2O5+ (SBSC) are being studied as possible cathode materials. SBSC are the subject of this investigation, which focuses on their crystal structure, electrochemical characteristics, single cell performance, and microstructure characterization. A tetragonal structure with P4/mmm space group and lattice parameter of 3.866 a, 3.866 b, c, and v = 113.40 is determined by the Rietveld refinement. The P4/mmm space group and lattice parameter of 3.866 are determined by the P4/mmm refinement. Precise polarization resistance (Rp) values of a half cell specimen on the SDC electrolyte were found to be 1.8 (600oC), 0.42 (700oC), and 0.13 (800oC) cm2 at 600, 700, and 800oC, respectively, while the peak power density of single cell Ni-SDC|SDC|SBSC was found to be 302 mW/cm2 at 700oC. All of the findings indicated that SBSC64 cathode is a more promising prospective cathode material for IT-SOFC than other cathode materials.
