Abstract: “A two-dimensional model based on the lattice Boltzmann method (LBM) is established to study the performance of solid oxide fuel cell (SOFC). A single phase multicomponent model is used to describe mass transport in the porous electrodes and fuel/air channels. Our results are compared with those from the literature and a good agreement is found. After model validation a parametric analysis is conducted to examine the effect of operating parameters on SOFC performance. The purpose of this paper is to examine the effect of the Kelvin force, caused by magnet particles deposited on cathode/electrolyte interface, on SOFC performance. The obtained results suggest that no magnetic field effect was observed for SOFC performance.”
