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 bipolar plate for a fuel cell is disclosed including a first unipolar plate having an active surface with a plurality of flowfield channels formed therein. The first unipolar plate further includes an inlet header disposed at a first end of the unipolar plate that is in communication with the active surface, and an outlet header disposed at a second end of the unipolar plate having an exhaust opening formed therethrough. A peripheral edge of the exhaust opening is chamfered and is also in communication with the active surface. The chamfered exhaust opening forms a water removal channel in the bipolar plate. A fuel cell stack including the bipolar plate is also disclosed.

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 stack assembly is disclosed that includes a porous member disposed within a flow path for a reactant. A fluid collection member is provided within the flow path adjacent to and in fluid communication with the porous member. The porous member and the fluid collection member cooperate to collect liquid water from the reactant flowing in the flow path, wherein the collected liquid water may be drained from the fluid collection member.
