Abstract
Certain fuel cell designs employ bipolar plate assemblies with internal coolant flow fields which comprise a coolant channel region and transition regions adjacent the coolant channel region. The temperature and/or pressure drop, and hence flow, of coolant over the coolant channel region can be non-uniform however, and this can have an adverse effect on cell performance. The coolant flow and temperature distribution can be modified and made more uniform by inserting an appropriate non-uniform porous insert in one or more of the coolant transition regions.
