| Abstract | Solid Oxide Fuel Cells (SOFCs) are of great interest due to their high energy efficiency, low emission level, and multiple fuel utilization. In this study, a mathematical model of a co-flow planar anode-supported SOFC has been developed. The model simultaneously solves mass transport equations coupled with electrochemical reaction, as well as transportation of electrons and ions through the respective spherical shaped electron and ion conducting particles inside the electrodes. The influence of electrode microstructure on cell performance was investigated. The investigation confirmed the strong effects of microstructure geometry, especially the electrochemical active surface area (Av), on the SOFC performance. The largest Av is achieved when the size and solid volumetric fraction of ion and electron conducting particles are equal. The model was validated with existing experimental results from the available literature. |
