POROUS FLOW FIELD PLATE FOR MOISTURE DISTRIBUTION CONTROL IN A FUEL CELL

摘要

A flow field plate for use in a fuel cell includes a porous, wettable plate body. A plurality of flow channels are arranged on the body such that an inlet portion of a first flow channel is adjacent an outlet portion of a second flow channel. Moisture from a fluid in the outlet portion of the second flow channel can move through the body of the porous, wettable plate from the outlet portion of the second flow channel toward the adjacent inlet portion of the first flow channel.
