Abstract

A 3D model of computational fluid dynamics for an anode solid oxide fuel cell is presented. This model incorporates important transport phenomena in a fuel cell such as heat transfer, mass transfer, electrode kinetics, and potential field. The simulation results of the model were compared with the available laboratory data in the same conditions that shows good agreement with other references. In this model, the effect of different parameters such as temperature, pressure, stoichiometry and electrolyte thickness on the fuel cell performance was investigated. The results of this model clearly describe the distribution of species, including reactants and products, temperature distribution, distribution potential, and distribution of current density. The results showed that the temperature, pressure and stoichiometry of the anode have a great effect on the performance of the cell so that each parameter increases the performance of the fuel cell performance. On the other hand, increasing the thickness of the electrolyte can have a negative effect on the performance of the fuel cell.
