Abstract

This study presents three-dimensional (3-D) channel design in single anode-supported solid oxide fuel cells (SOFCs). Because of their high operating temperatures, the thermal management is important in the full system. There has been speculation that flow field design may play an important role in the overall heat transfer in SOFCs. The parametric study was performed for investigation the effect of the heat transfer in a single cell with several flow field designs. The temperature distribution and the fuel cell performance were discussed. The model was validated with experimental data from Rogers et al [1]. The conservations of mass, momentum, energy and species were solved by using the commercial computational fluid dynamics code, FLUENT??, in the developed model. The add-on FLUENT?? SOFC module is implemented to model the electrochemical reactions, loss mechanisms, i.e. activation polarization and ohmic polarization, and related electrochemical parameters throughout the cell.
