Heat And Mass Transfer Of Reforming Gas In Porous Media

Solid oxide fuel cells (SOFC) were expected to become one of the most potential energy sources in 21th Century. In many aspects the porous support structure of an integrated-planner SOFC were prior over other types of SOFC. Therefore, it should fully developed on next generation SOFC. Simulate of chemical reacting gas, heat and mass transfer in the porous support structure of an integrated-planar SOFC by a three-dimensional calculation method. This paper found physical model and mathematical model. This paper discretized computational domain and mathematical model with iteration method. This paper analyzed effect of temperature, pressure, the molar ratio of steam to methane, porosity on reaction. The results showed methane conversion decreasing with the molar ratio of steam to methane. It should suggest that the porosity of 0.4 was the optimum choice. It was suggested that 2 molar ratio was optimum by the compute of thermodynamics, and so on. It found that well assimilated by comparison of the results with other experimental data available in the literature. It was expected that it can provide the basis for the design and cognition of SOFC.
