Abstract
The microstructure of a Solid Oxide Fuel Cell consists of metallic and ceramic grains, as well as porous micro-channels with characteristic diameters below 1 micrometer. Each phase within the microstructure plays a critical role in enabling electrochemical phenomena such as current flow, gas diffusion, and chemical reactions at phase boundaries. In computational modeling of these processes, the simulation domain can be constructed using stacks of scanning electron microscopy micrographs. The Finite Element Method is applied in this research to evaluate how geometry and mesh construction, using common FEM-adjacent algorithms, affect the simulation-based prediction of overpotential at the SOFC anode. MATLAB (MathWorks) is employed to process three-dimensional microstructure reconstructions, generate geometry and Finite Element Method meshes, and solve the resulting system of equations. The impact of image processing steps—such as resampling, surface fitting, and smoothing—is assessed. A resolution sensitivity study is conducted, and practical recommendations are proposed for applying Finite Element Method to model microscale transport phenomena in Solid Oxide Fuel Cells.
