Multi-scale Modeling Methodology for Computer Aided Design of a Solid Oxide Fuel Cell Stack

摘要

This paper presents the multi-scale modeling strategy developed for the design of a solid oxide fuel cell (SOFC) stack. Around the main models which are the repeat element model (in simplified 2D and CFD), specific model for experiments have been developed to identify key parameters for the main models. Features of the different models used are presented. The CFD model and the simplified 2D model are compared in their sensitivity on transport properties and operating parameters. Results of the multi-objective optimization performed on the repeat element design parameters are presented.
