Abstract:
A key component of the clean energy revolution is anticipated to be the direct and efficient conversion of chemical energy into electrical energy via Solid Oxide Fuel Cells (SOFC). The purpose of this effort was to simulate and model the operation of solid oxide fuel cells. In MATHLAB software modeling methodology, the steps that were followed were the mathematical calculation of current density's independent variables, the calculation of variables that depend on current density, and the display of the result. This model's results showed that the polarization curve of a SOFC was dominated by concentration loss polarization between 1.2 – 1.4 volts with current density, activation polarization between 0.6 − 1.2 volts, and ohmic loss polarization between 0 − 0.6 volts. To produce electrical energy, the chemical species diffuses more quickly at the anode side than at the cathode side. Studies have also been conducted on the effects of design and operating circumstances on cell performance. The outcome indicated that while the power density stayed proportionate to current density, the cell potential decreased as current density increased. Validation of the expected performance was done using experimental data from the literature excellent agreement between the anticipated and experimental values was observed.
