Development And Validation

In this paper, we report our ongoing team efforts (which are being funded by the US Department of Energy) toward the development and validation of a three-dimensional, two-phase, comprehensive PEM (polymer electrolyte membrane) fuel cell model. Specifically, we report our progress in following areas: i) a channel two-phase flow submodel to account for the presence of liquid water in flow channels and its effect; ii) an approximate but robust approach for taking MPL (microporous layer) effect into account; iii) an investigation into the effect of cell segmenting; and iv) an ongoing effort in model validation.

For the last couple of years, we have been working on developing and validating a three-dimensional, two-phase, comprehensive PEM (polymer electrolyte membrane) fuel cell model, and our efforts were funded by the US Department of Energy. In this paper, we provide an up-to-date progress report on our team efforts. Specifically, we present comparisons of simulation results (liquid-water saturation distribution) computed by our improved partially two-phase and fully two-phase models. We also present sample model-validation results by comparing model prediction with experimental data.

Computational Capability

In this paper, we report the progress made in our project recently funded by the US Department of Energy (DOE) toward developing a computational capability, which includes a two-phase, three-dimensional PEM (polymer electrolyte membrane) fuel cell model and its coupling with DAKOTA (a design and optimization toolkit developed and being enhanced by Sandia National Laboratories). We first present a brief literature survey in which the prominent/notable PEM fuel cell models developed by various researchers or groups are reviewed. Next, we describe the two-phase, three-dimensional PEM fuel cell model being developed, tested, and later validated by experimental data. Results from case studies are presented to illustrate the utility of our comprehensive, integrated cell model. The coupling between the PEM fuel cell model and DAKOTA is briefly discussed. Our efforts in this DOE-funded project are focused on developing a validated computational capability that can be employed for PEM fuel cell design and optimization.

Water transport in the Porous Transport Layer (PTL) plays an important role in the efficient operation of polymer electrolyte membrane fuel cells (PEMFC). Excessive water content as well as dry operating conditions are unfavorable for efficient and reliable operation of the fuel cell. The effect of thermal conductivity and porosity on water management are investigated by simulating two-phase flow in the PTL of the fuel cell using a network model. In the model, the PTL consists of a pore-phase and a solid-phase. Different models of the PTLs are generated using independent Weibull distributions for the pore-phase and the solid-phase. The specific arrangement of the pores and solid elements is varied to obtain different PTL realizations for the same Weibull parameters. The properties of PTL are varied by changing the porosity and thermal conductivity. The parameters affecting operating conditions include the temperature, relative humidity in the flow channel and voltage and current density. A parametric study of different solid-phase distributions of the PTL and its effect on thermal, vapor and liquid transport in the PTL under different operating conditions are discussed.
