Abstract

This paper reports a new 3D isothermal, steady state electrochemical modeling study for tubular solid oxide fuel cells where the testing setup is studied in order to improve fuel distribution and geometry. For the model validation, an experimental voltage-current density curve measured in house was used. This study focuses on the cell testing setup and is used to optimize the testing geometry for improved testing conditions. The mathematical model consists of coupling fluid dynamics, electrical conduction, and diffusion physics. The model indicates that flow mal-distribution may be of concern and may affect cell performance. In addition, concentrations of current densities throughout the solid oxide fuel cell may cause some hot spots. Finally, the model is able to predict the cell voltage-current density of the cell very well when compared to experimental data.
