Simulation of Heat Transfer and Effects on Reaction-Coupled Transport Processes in SOFCs

Summary, in English

For anode-supported plate solid oxide fuel cells (SOFCs),

the size of the porous anode is bigger than that of the fuel gas

flow duct in terms of thickness and cross-sectional area. The

heat transfer rates are controlled by various operating and

design parameters, and have significant effects on chemical

reactions and coupled transport processes. In this study, the

considered composite duct is relevant for an intermediate

temperature (600-800oC) plate design and consists of a porous

anode layer for the internal reforming reactions of methane, the

fuel gas flow duct and solid plate. A fully three-dimensional

calculation method is developed to simulate and analyze heat

transfer and combined effects on internal reforming/ electrochemical

reactions and the coupled transport processes, with

purpose to reveal the importance of various parameters. The

results show that the operating temperatures have significant

effects on the chemical reactions, fuel gas distribution and

overall performance.
