CFD Analysis of Elementary-kinetic Chemical Reactions and Effects on Transport Processes in Anodes of Solid Oxide Fuel Cells
Solid oxide fuel cell (SOFC) is one of most promising types of fuel cells with advantages of high efficiencies, flexible fuel types.As a device directly converting the free energy of chemical reactant to electrical energy and heat, the performance of SOFC is strongly affected by the chemical and electro-chemical reactions occurring in the porous anode coupled with mass, momentum and heat transfer processes.A 3D CFD model has been developed by using in-house code to analyze the various processes coupled with elementary surface reactions occurring in SOFCs anode, to identify the effects between transfer processes and some elementary reactions occurring in the anode.It shows that single step elementary reaction can affect the distribution of surface species, but not remarkable on global conditions such as temperature and gas distribution.On the other hand, global parameters including temperature, porous characteristics affect the surface species distribution and elementary reaction processes largely.
