Abstract
Abstract
The current paper presents the results of a parametric study conducted with a previously described three-dimensional, non-isothermal computational fluid dynamics model of a proton exchange membrane fuel cell, which was developed and discussed in detail in part 1 of this series. The effects of several operating, design, and material parameters on fuel cell performance has been investigated in detail. The results of the current study helped identifying critical parameters and shed insight into the physical mechanisms leading to a fuel cell performance under various operating conditions. Furthermore, the current study demonstrates the use of a comprehensive three-dimensional single-phase model as a design and optimization tool.
