摘要：
In this study, the influence of radiation heat transfer within a planar SOFC is investigated. The numerical model is made by performing two-dimension mathematical model describing mass, momentum and heat transport phenomena coupled with electrochemical reactions. The finite volume method is used to solve the governing equations. Compared with literature results, the simulations show that radiation reduces temperature gradients and has a significant effect on enhancing heat transfer within the SOFC and counter balancing thermal dissipation induced by activation, concentration and ohmic polarisations. Thus, it must be included for an accurate model.
