FUEL CELL WITH ENHANCED CROSS-FLOW SERPENTINE FLOW FIELDS

摘要

A serpentine channel is split into independent serpentine channels with individual inlets from a common inlet manifold such that a high pressure differential is maintained between flow channel and the U bends causing a cross-flow of the reactant through the porous diffusion layer from the flow channel to the U bends, the layout of the flow field being such that the cross-flow is higher in the oxygen depleted portion of the adjacent serpentine flow field.
