Parametric study with simulation of transport phenomenon of a solid oxide fuel cell

Abstract

The solid oxide fuel cells (SOFC) have the potential to become one of the efficient and cost-effective direct management systems for converting a wide variety of fuels into electricity. In this study, we developed a three-dimensional model with a single phase of a solid oxide fuel cell (SOFC) planar fueled with hydrogen to improve the fundamental understanding of transport phenomena and performance in the SOFC. The simulations were carried out using COMSOL Multiphysics software (version 5.4) based on the finite element method for solving the continuity equation (mass transport), the conservation equation (transport of the moment of transport). gas, ordinary diffusion transport of chemical species, heat transfer, charge transport), a parametric study was done to examine the effect of certain parameters such as the operating pressure, the temperature and porosity the porosity of the electrodes) the gas diffusion layer (GDL) on the performance of the SOFC stack for boundary conditions.
