A novel pseudo-2D computationally-efficient approach is developed by modal analysis for modeling a single cell of a high-temperature solid oxide fuel cell. The model is called a pseudo-2D as it fully models the flow in the flow direction and captures the effects of diffusion in the transverse direction using modal analysis. To improve convergence, the model uses a precalculated relation between the cell temperature and current density without explicitly solving the energy equation. The model is shown to agree with results obtained by previous researches and the solution convergence is significantly quicker than 3D CFD simulations. The model will be used in the future works of this research group for stack modeling, optimization, and online control of the cell.
