Numerical simulation of heat and mass transfer in solid oxide fuel cell in presence of magnet particles deposited in cathode side

摘要

A two-dimensional model based on the lattice Boltzmann method (LBM) is established to study the solid oxide fuel cell performance. 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 the SOFC performance. The purpose of this paper is to examine the Kelvin force effect, caused by magnet particles deposited on a cathode/electrolyte interface, on the SOFC performance. The obtained results suggest that no magnetic field effect was observed for SOFC performance.
