Planar Solid-Oxide Fuel Cell Research and Development

Abstract

Numerical simulation capabilities to perform flowfield analysis and sensitivity analysis of solid oxide fuel cells (SOFCs) have been developed. A three-dimensional, implicit, multi-species fuel cell solver is modified to analyze cell geometries supplied by NexTech Materials (NexTech). Four different NexTech cell configurations of varying complexities have been analyzed in this study. A capability to perform thermo-mechanical analysis of NexTech cells is developed by coupling the fuel cell code with the structures code. The capability was initially developed for a simplified cell that also included sensitivity analysis of thermo-mechanical variables. Sensitivity derivatives are computed using the direct differentiation method in the fuel cell and structures codes.
