First-principles modeling of Solid Oxide Fuel Cells accounting for electrodes geometry and microstructure

In this work a 2-D isothermal axial-symmetric model of an electrolyte supported Solid Oxide Fuel Cell (SOFC) has been developed.The model is built on COMSOL Multiphysics, a finite element simulation commercial software. The model tries to describe the complex phenomena that occur within a SOFC through a first principles-based approach. That allows the description of the electrochemical and physical phenomena starting from the macroscale, continuing with the mesoscale and down to the microscale.
