Transport Phenomena in a Banded Solid Oxide Fuel Cell Stack—Part 1: Model and Validation

This paper primarily focuses on the formulation and validation of mathematical numerical models for a new electrolyte-supported solid oxide fuel cell stack. By leveraging modeling, main goal is to deepen understanding operational aspects transport phenomena within this system. The developed are implemented in ANSYS, Inc., Fluent software, which enables range simulations. To validate models, stack fabrication methodology, prototype construction, conducted electrochemical tests were proposed. simulated current-voltage characteristics two different operating temperatures three compositions compared with experimental measurements satisfactory agreement. counter-flow configuration was co-flow arrangement. simulation has demonstrated its efficacy identifying possible design imperfections enhancing conditions Moreover, model further used, Part 2 paper, analyze improvement options implementation next stage prototype.
