Conventional energy sources such as petroleum and coal are currently the primary sources for electricity production. However, these energy sources are depleting, and are also unfriendly to the environment. Renewable energy sources such as solar energy, wind energy, photovoltaic cell energy etc. are very effective in reducing the greenhouse gas emissions serving as cleaner alternatives. Solid oxide fuel cells (SOFC) serve as one such alternate clean source of energy. These unlike other fuel cells which can only operate with specific fuel sources, exhibit fuel flexibility by operating at high temperatures. These high temperature operations however come with several inherent challenges such as suitable choice of material, stability of the auxiliary systems and so on, for the optimum performance of the fuel cell. Hence critical understanding of corelation between high temperatures and the performance of the SOFC is required so that the controlling factors can be optimised further to suit more small-scale applications. To aid this aspect in our study, simulation of a three-dimensional modelled single cell planar solid oxide fuel cell was performed under steady-state and counter-current flow condition in the temperature range of 500 degree centigrade to 1200 degree centigrade using a computational dynamics software, COMSOL Multiphysics. The choice of materials for the fuel cell involved the use of, nickel oxide as anode, lanthanum strontium cobalt ferrite as cathode and yttria-stabilized zirconia the electrolyte. Hydrogen was supplied as anode side fuel while oxygen was fed as the cathode side fuel. The performance of the fuel cell was then determined from the polarization and power characteristics, which were then analyzed, and it was finally interpreted that with the increase in operating temperature, the performance of the solid oxide fuel cell increases.
