Parallel channel flow field with manifold openings is widely used in Proton exchange membrane fuel cells (PEMFCs) because of its low-pressure drop and easiness of manufacture. This research presents a hydrodynamic model to describe the airflow distribution, and the predicted pressure differences are validated by experiments. We also investigate the influences of the flow rate, the geometry of header and the length ratio of manifold opening to header region on the airflow distribution. Therefore, the optimal strategy is proposed based on an overall consideration of uniformity and configuration in the fuel-cell plate for application. (c) 2008 Elsevier B.V. All rights reserved.
