摘要： A bipolar plate for a fuel cell is provided that includes a flowfield having an active surface with an inlet region and an outlet region. The active surface of the flowfield is in communication with the inlet region and the outlet region and has at least one flow channel formed therein. The at least one flow channel further has a cross-sectional area at the outlet region that is less than a cross-sectional area at the inlet region. In particular embodiments, the at least one flow channel is bifurcated. A fuel cell stack including a fuel cell and the bipolar plate is also provided.

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 fuel cell plate having a first plate having an inlet aperture and a second plate disposed against the first forming a conduit. The conduit has a continuous seam formed between the first plate and the second plate to facilitate a transport of water to the outlet aperture. The plates can include various indentations and protuberances that form portions of the conduit. The fuel cell plate is well suited for use in a vehicle fuel cell stack for reducing water retention in a fuel cell without increasing the number of required components and fabrication cost of the fuel cell plate.
