Meso-scale structures significantly influence fuel cell performance and durability.
We have modelled the multiphysics processes in the solid oxide fuel cell cathode-electrolyte interfaces considering the detailed distribution and geometry of the ionic conducting phase, the electronic conducting phase, and the pores.
The model is solved using COMSOL Multiphysics and results provide insights into the design of an optimal geometry for maximum electrode performance as a function of meso-scale structure and constituent material properties.
