This paper describes the development and application of a novel computational fluid dynamics model which allows the investigation of large solid oxide fuel cell stacks in practical computation times. Comparisons with a previously verified model match quantitatively to within 3% difference for all parameters of a benchmark case and solve within 1.5% the computation time for parallel flows of air and fuel in a cell, verifying the present model as a practical option in stack design. The model is used to demonstrate that the distribution of flow rates to each cell in a 100 cell stack significantly affects the temperature distribution and overall electrochemical performance. In a further analysis, it is quantitatively demonstrated that it would be misleading to attempt to predict performance or optimise manifold designs based on a model with uncoupled transport and electrochemistry. |
