Professor Naoki Shikazono's research lab specializes in computational materials science and energy conversion systems, with a focus on multi-scale modeling of solid oxide fuel cells (SOFCs). The lab employs advanced numerical methods such as the lattice Boltzmann method to simulate complex transport phenomena—electronic, ionic, and gaseous—within three-dimensional microstructures reconstructed from FIB-SEM imaging. Key research directions include understanding electrochemical reaction mechanisms at the three-phase boundary, optimizing anode performance through microstructure design, and investigating the effects of operational parameters like steam partial pressure and domain size on overpotential. The lab bridges experimental microstructure data with predictive simulations to advance next-generation energy materials.

A three-dimensional numerical simulation of the solid oxide fuel cell (SOFC) anode overpotential is conducted in a microstructure which is reconstructed by dual-beam focused ion beam–scanning electron microscopy (FIB-SEM). Gaseous, ionic, and electronic transport equations are solved by a lattice Boltzmann method with electrochemical reaction at the three-phase boundary. The predicted anode overpotential agrees with the experimental data at the fuel supply of , while it is larger than the data a
