There are similarities among various transport processes in solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs), but also some differences. The present work concerns modeling and numerical analysis of heat, mass transfer/species flow, two-phase transport and effects on the cell performance in SOFCs and PEMFCs. Numerical calculation methods are further developed to enable predictions of convective heat transfer and pressure drop in flow ducts of the fuel and the

The composite duct consists of a porous layer, gas flow duct and/or solid current inter-connector (or -collector). The results from this study are applicable for other investigations considering overall fuel cell modeling and system studies, as well as the emerging field of micro-reactor engineering.
