Abstract
In this paper, modeling and simulations are carried out using COMSOL Multiphysics. A three-dimensional model is developed for a planar intermediate temperature (IT) solid oxide fuel cell (SOFC). A parametric study has been carried out to analyze the performance of SOFC.Simulations reveal some promising features and enhanced performance of SOFC. It is shown that the maximum value of power (4–3.3) kW/m2 still remains higher with significant rise of temperature (600 °C–1000 °C), nearly 0.15 kW/m2 is the very small loss of power per 100 °C rise of temperature. Results have shown that the electrolytic current density is (6700–5500) A/m2 for peak value of power (4–3.3) kW/m2 with increase of temperature (600 °C–1000 °C). For model validation we have plotted a comparison of average current density.
