To achieve higher efficiency and output density in next generation fuel cells, lowering the irreversible losses associated with reaction and transport in the cell, especially the electrode overpotential, is inevitable. For this purpose, it is important to understand the processes involved in the electrode reaction. It is thus necessary to utilize simulations at different spatial and temporal scales as well as to collaborate with experimental observations. Multi-scale simulation approaches reported so far does not allow us to bridge atomistic level chemical reaction and micro-meter scale transport phenomena, which is necessary in simulating the fuel cell electrode reactions. As a part of such efforts, I will introduce the recent simulation efforts on the anode of SOFC anode. In collaborations with researchers from a variety of disciplines, improvement of anode kinetics is tackled from the perspectives of reaction at triple phase boundary and microstructure of porous anode.
