Abstract

There are sources of heat generation and absorbtion in SOFCs, which are affected by gas parameters in the fuel cells. These sources cause heat transfer to the flowing gases. The pressure drop caused by flow resistance in the channels has effects on the distribution of temperature and gas flow rate. Some modeling work have been carried out under the assumption of laminar flow during last few years. The present work concerns a review of heat transfer and gas flow modeling developments in the SOFCs as well as some new modeling development. The different models are comparied in terms of model level (unit or stack, system), flow type (cross-, co- or counter-flow) and developed or developing flow, thermal source considered, boundaries used in the model, models of heat transfer to the gas and whether the pressure drops were considered in the model. Some useful remarks and conclusions are drawn. Results from a new modeling approach is also provided.
