Abstract

This report provides instructions for use of the two-dimensional solid oxide fuel cell multi-physics (2D SOFC-MP) modeling code developed at Pacific Northwest National Laboratory (PNNL). This research software package evaluates the electrochemical performance and temperature distribution of multi-cell co-flow and counter-flow solid oxide fuel cell (SOFC) stacks. These types of analyses are useful to stack designers to evaluate the effect of cell design, geometric parameters, material properties, electrochemical properties, thermal boundary conditions, and operating conditions on stack performance. This report briefly presents an overview of the code followed by detailed instructions and examples for installation, model pre-processing, usage, solution, and results post-processing with the software. Several demonstration cases are presented which highlight the types of engineering analyses that can be performed with the software.
