    摘要： A device and method to extract water from a moisture-rich fuel cell flowpath. A water transport unit is integrated into the fuel cell so that liquid water stagnation within flow channels and manifolds is reduced. In one embodiment, the device includes numerous flowpaths that include an active region and an inactive region. The water transport unit includes a hydrophilic member such that upon passage of a fluid with the excess water through the inactive region of the device flowpath and into the presence of the hydrophilic member, it absorbs excess water from the fluid.

    摘要： A plate for a fuel cell is disclosed, wherein an inlet aperture is disposed at a first end of the plate and an outlet aperture is disposed at a second end of the plate. The plate includes a first side and a second side. The first side of the plate has a flow field formed therein between the inlet aperture and the outlet aperture, the flow field having a plurality of flow channels formed therein, the plurality of flow channels in communication with a plurality of outlet ports formed in the plate. The second side of the plate has a plurality of drainage channels formed therein adjacent the outlet aperture, the plurality of drainage channels in fluid communication with the outlet ports and the outlet aperture, wherein a cross-sectional area occupied by each of the plurality of flow channels is substantially equal to a cross-sectional area occupied by each of the plurality of drainage channels.
