Study Of The Effect Of Temperature On Performance Of Sofc Made From Ni-Gdc Anode, Lscf-Sdccathode, And Ysz Electrolyte

Abstract

The energy crisis and global warming, both of which are driven by the combustion of fossil fuels, have drawn a lot of attention to the need for researchers to identify alternative energy sources to minimize fossil fuel consumption. Because of the great efficiency and environmental friendliness, solid oxide fuel cells are a viable alternative energy source. Modeling and Simulation of the performance of Solid Oxide Fuel Cells was the goal of this work. A solid oxide fuel cell (SOFC) steady state mathematical model has been constructed, which can predict performance under varied operating and design conditions. The examination of critical parameters that have a significant impact on SOFC performance was investigated with Mathematical modeling. The calculation of independent variables of current density, temperature, calculation of variables that are dependent on current density, and temperature were the procedures followed in MATLAB software modeling methodologies. The modeling result revealed that Ohmic resistance is the largest resistance, followed by activation polarization in SOFC. Whereas, concentration polarization is the least resistance. Anode conductivity increases at a faster rate than cathode conductivity with temperature. This indicates that the chemical species diff uses at a faster rate at the Ni−GDC side than at the LSCF−SDC side in order to generate electrical energy. The impact of operating and design conditions on cell performance has also been studied. The result showed that the cell potential fall down as current density increased, however the power density remained proportional to current density which consistent to experimental data.
