Abstract

Advanced materials are critical to driving further progress in solid oxide fuel cell technology to improve efficiency and accommodate a broader range of fuels. Samarium and Yttrium doped perovskite is synthesized via Sol-gel method. According to XRD examination, the predominant phase possesses a cubic crystal structure derived from the Fm3m space group (number 225). A microscope examination reveals the formation of agglomeration and porosity. The SAED patterns of Sm0.5Ce0.5NiO3 and Y0.5Ce0.5NiO3 confirm the poly crystalline nature. As samarium and yttrium are introduced, greater oxygen vacancies form, which impacts the ways grains and grain boundaries form in the material. A combination of various parameters, variations in conductivity and activation energy obey a monotonic trend. Impedance measurement shows a substantial improvement in conductivity is observed for grain and grain boundaries.


Keywords: Perovskite, SOFC, Oxygen vacancies, Impedance.
