Transient Bi-Domain 1D PEFC Model

摘要

A bi-domain transient 1D PEFC model is developed which, while retaining the low computational cost of 1D models, takes into account the different pathways for multiphase transport under the rib and channel domains. This concept allows setting different boundary conditions for liquid transport at the channel-GDL and the rib-GDL interfaces. The model is thus suitable for studying the temporal cell behavior more accurately than 1D models, but still with comparable computation times.
