abstract = {In this paper, a computational model is used to study the
distributions of several key parameters and the performance
of a fuel cell with an active area of 200 . The results
reveal that the model is capable of predicting the overall
behavior in good agreement with experimental data and with
superior resolution. Polarization curves are compared and
cell voltage prediction deviations are within of
experimental values. The predicted current density
distribution is very close to both the experimentally
measured results and a volume-average approach based on rate
equations. Local variations of current density, oxygen, and
water mole fraction change significantly from under-rib
regions to under-channel regions. The serpentine type flow
path leads to greater pressure gradients, but is beneficial
to gas bypassing through the gas diffusion layers. This type
of flow path helps to redistribute the species and current
density distributions. Never before has it been possible to
construct computational models capable of predicting
fine-scale details in local current density; details which
were not captured neither by previous models nor by
present-day experiments.},
