Perspectives on Lattice Boltzmann Modeling of Transport Processes with Electrochemical Reactions in SOFCs
Författare
Summary, in English
It is concluded that LBM can be used to evaluate the microscopic effect of electrochemical reactions on the transport processes. Case studies are carried out on the current density and the concentration distribution of H2 by changing the porosity, percentage of active reaction sites and particle size. It is shown that an increase in porosity decreases the current density throughout the porous domain while an increase in percentage of active sites has a positive increase in current density. The concentration of H2 decreases throughout the cell when the porosity is increased from 30% to 50%. As a suggestion for future improvements, it might be a good idea to have the active reaction sites placed out in a graded manner with a high density of reaction sites where it is needed
