A THREE-DIMENSIONAL TWO-PHASE MODEL FOR SIMULATING PEM FUEL CELL PERFORMANCE

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.
