Formatted abstract
The aim of this study is to develop a computational fluid dynamics (CFD) model that will be used to assess the viability of metal foam in a Proton Exchange Membrane Fuel Cell (PEMFC) interconnect context. The software used for this is ANSYS FLUENT 13.0. The mesh is generated, tested for independence and validated. An accurate fuel cell environment is produced using variables from literature and theory and results are then obtained for temperature, pressure drop and heat transfer in the metal foam volume. These are presented and their accuracy is verified against theory and previous experiments. The temperature gradient is found to be shallow and therefore not conducive to the creation of thermal stresses. The model also shows that pressure drop over the foam volume is highly dependent on velocity and closely matches values predicted by a non-Darcy formulation. Comparisons are made with current serpentine flow plate designs and metal foams are found to provide similar heat transfer abilities, with slightly less uniformity in temperature. However it is concluded that metals foams also hold significant advantages, such as low weight, high electrical conductivity and minimal parasitic losses.
