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.

摘要： A fuel cell in a fuel cell stack that provides a transition from nested bipolar plates in the active region of the stack to non-nested bipolar plates in the inactive regions of the stack without giving up the reduced stack thickness provided by the nested plates or changing the size of the flow channels. Particularly, the diffusion media layers in the fuel cells are removed in the inactive regions where the bipolar plates are non-nested so that the volume necessary to maintain the size of the flow channels is provided without the need to increase the distance between adjacent MEAs. A thin shim can be provided between the membranes and the plates in the inactive regions to support the membrane where the diffusion media layer has been removed to prevent the membrane from intruding into the flow channels and blocking the reactive flow.

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.
