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