摘要： A seal structure is disclosed for forming a substantially fluid tight seal between a UEA and a plate of a fuel cell system, the seal structure including a sealing member formed in one fuel cell plate, a seal support adapted to span feed area channels in an adjacent fuel cell plate, and a seal adapted to cooperate with a UEA disposed between the fuel cell plates, the sealing member, and the seal support to form a substantially fluid tight seal between the UEA and the one fuel cell plate. The seal structure militates against a leakage of fluids from the fuel cell system, facilitates the maintenance of a velocity of a reactant flow in the fuel cell system, and a cost thereof is minimized.

摘要： A fuel cell component including a body disposed along a plane and having a boundary past which a reactant and water flows is provided. The boundary has a discontinuous edge adapted to militate against a pinning of the water at the edge. The fuel cell component may be a bipolar plate having a port hole with the discontinuous edge. The fuel cell component may be a subgasket for a fuel cell having a boundary with the discontinuous edge. The discontinuous edge facilitates a transportation of water from an upper surface of the fuel cell component to a lower surface of the fuel cell component.

摘要： A fuel cell stack that includes straight cathode flow channels and straight anode flow channels through a seal area between bipolar plates in the stack. The fuel cell stack includes a seal that extends around the active area of the stack and between the stack headers and the active area. At the locations where the cathode flow channels extend through a seal area to the cathode input header and the cathode outlet header, and the anode flow channels extend through a seal area to the anode input header and the anode output header, the diffusion media layer on one side of the membrane is extended to provide the seal load. Alternately, shims can be used to carry the seal load.
