Thermal and Electrical Coupling in Stacks

  • Brian Wetton
Part of the Topics in Applied Physics book series (TAP, volume 113)


Many of the other chapters of this book are devoted to understanding several key aspects of PEMFCs at a fundamental but local level. These include membrane transport, the influence of catalyst layer structure on performance and the nature of two-phase flow (liquid, water, and gas) in electrodes. However, if one has accurate parametric descriptions of these phenomena, from detailed models fitted to experimental measurements, the question remains how these locally fitted models will combine with more well-understood phenomena of gas, heat, and electrical transport to determine overall systemperformance, at the unit cell or stack level. This is the question addressed in this chapter, in which a stack level computational model of a PEMFC stack is presented and discretized, and an iterative strategy is described. This computational model is capable of simulating thermal and electrical interactions of unit cells in large stacks. It is computationally efficient, requiring only a...

The work described here is a summary of ideas developed by a group of academic mathematicians working with scientists from Ballard, including Peter Berg, Radu Bradean, Atife Caglar, Paul Chang, Gwang-Soo Kim, Keith Promislow, Jean St-Pierre, John Stockie, and Juergen Stumper. The group is funded by both Ballard and the Mathematics of Information Technology and Complex Systems (MITACS) Network Centre of Excellence in Canada.
