Abstract: | Mass, heat and momentum transport processes are strongly coupled by internal chemical reforming reactions in planar design
solid oxide fuel cell (SOFC) anodes. In this paper, a three-dimensional computational fluid dynamics approach is applied to
simulate and analyze reforming reactions of methane and various transport processes in a duct relevant for SOFC anodes. The
results show that the anode duct design and operating parameters, grouped as three characteristic ratios, are significant
for the chemical reactions and further for multi-species distribution, fuel gas transport and heat transfer in the sub-domains
of the anode. |
