Description:

Objective:

The overall objective of this research project is to understand how a polymer-electrolyte fuel cell operates, with specific emphasis on the relevant transport phenomena.

Approach:

To accomplish this objective, a model is being developed that accounts for the various regions within the fuel-cell sandwich. This model is pseudo two-dimensional (one-dimensional plus integration down the channel) and nonisothermal. The core of the model is the governing equations for diffusion, kinetics, electrochemical effects, and flooding of the porous matrix because of liquid water (i.e., saturation effects), throughout the various layers of the sandwich. The model should yield accurate results compared to the literature and provide new and comprehensive understanding of how a fuel cell works.

Supplemental Keywords:

fellowship, automotive fuel cells, electrochemical processes, fuel-cell sandwich, polymer-electrolyte fuel cell.
