D212 2D Numerical Simulation of Anode Supported Planar SOFC Considering Microstructure of Electrodes

Abstract

A two-dimensional comprehensive CFD model for anode-supported planner solid oxide fuel cells (SOFCs) is developed to study the performance the cells. The electrode microstructures of the anodes are quantified using FIB-SEM measurements and implemented to the simulation. The model is verified from a short stack experiment with a standard power output of 100W. The simulation results have a good agreement with experimental data, and reveal the relationships between the cell performance and the electrode microstructure. In addition, effects of temperature on the potential loss are presented.
