In PEM fuel cells, turbulent flow occurs at locations of large characteristic length scale such as the stack headers and external manifold.Design of these flow passages has impacts on the overall pressure drop, flow distribution to unit cells, degradation (start-up and shut-down), safety, requirements for the balance-of-plant, etc.This talk will give an overview on the progress and current status of numerical and experimental studies on turbulent flows encountered in PEM fuel cells.Simulation and experimental results of the flow field and dynamics in a pair of model headers will be presented.Insights and implications from these results to practical fuel cell design and operation will be discussed.
