Modeling of Flat-Tube High Power Density Solid Oxide Fuel Cells (HPD SOFCs)Laura Schaefer and Yixin Lu
Materials and Storage
Planar solid oxide fuel cells (SOFCs) result in shorter current-collection pathways, while tubular SOFCs are more durable and are suitable for hybrid power-generation applications. Combining the best attributes of both results in the flat-tube design, the performance of which must be quantified.
Application and Benefits
- Flat-tube HPD SOFCs operate best in stacks.
- Their geometry allows for tighter clustering than tubular SOFCs.
- Their sealed construction make them suitable for high-pressure operation with a turbine-based bottoming cycle.
- Develop transport property relations.
- Investigate electrochemical reactions under varying operating conditions.
- Create an electrical circuit model.
- Integrate all three models to gain insight into local and total cell behavior.
