Gas flow and heat transfer with internal reforming reactions in an anode duct of SOFCs

Abstract
A fully three-dimensional calculation method has been farther developed to simulate and analyze internal reforming and its effects on various processes in a thick anode duct. In this study, the composite duct consists of a porous anode, the flow duct and solid current connector. Momentum and heat transport together with gas species equations have been solved by coupled source terms and variable thermophysical properties (such as density, viscosity, specific heat, etc.) of the fuel gas mixture. The fuel cell conditions such as the combined thermal boundary conditions on solid walls, mass balances (generation and consumption) associated with the reactions and gas permeation to/from the porous electrode are applied in the analysis.
