The cross flow in proton exchange membrane fuel cells (PEMFCs) plays an important role in changing the transport pattern and performance. In this study, three-dimensional numerical simulations are carried out to investigate the effect of induced cross flow on the flow pattern and performance of...

Purging a polymer electrolyte membrane fuel cell (PEMFC) with dry N2 to remove water in the catalyst layer and the membrane during shutdown is necessary for ensuring successful startup and avoiding damages from the freeze/thaw cycling during cold-start. However, carrying N2 onboard may be...
