WICKING LAYER FOR MANAGING MOISTURE DISTRIBUTION IN A FUEL CELL

摘要

An exemplary device for managing moisture content within a fuel cell includes a reactant distribution plate having a plurality of members that establish reactant flow channels that are open on at least one side of the plate. A wicking layer is against the one side of the plate. The wicking layer includes a first portion that is uninterrupted and covers over at least some of the channels. A second portion of the wicking layer extends along ends of at least some of the members such that sections of the channels coextensive with the second portion are open toward the one side.
