    Abstract: The method includes providing a component of an assembly having an interior portion and a peripheral portion and adhering separate strips of an adhesive tape to the peripheral portion of the component to surround the interior portion. The short side of a first strip is positioned adjacent a second strip. The adhesive tape includes an adhesive disposed on a backing, and the adhesive includes an amorphous fluoropolymer. The method further includes applying at least one of heat or pressure to the separate strips such that the adhesive flows seals any gap between the first and second strips and crosslinks. The method can be useful, for example, when the assembly is an electrochemical cell assembly and when the component includes at least one of an electrolyte membrane or a current collector.

    Abstract translation: 该方法包括提供具有内部部分和外围部分的组件的部件，并将胶带的单独条带粘附到部件的外围部分以包围内部部分。 第一条带的短边位于第二条带附近。 胶带包括设置在背衬上的粘合剂，并且粘合剂包括无定形含氟聚合物。 该方法还包括对分开的条施加热量或压力中的至少一个，使得粘合剂流动密封第一和第二条带之间的任何间隙并交联。 例如，当组件是电化学电池组件时并且当组件包括电解质膜或集电器中的至少一个时，该方法可能是有用的。

    Abstract: A proton exchange membrane fuel cell stack includes two or more plate assemblies stacked together. Each plate assembly includes a membrane electrode assembly (MEA) disposed between a first plate and second plate. One of the first and second plates is an anode plate and the other is a cathode plate. The first and second plates each include a first side facing the MEA and a second side facing away from the MEA. The plates include flow fields on the first sides and gas manifold holes coupled to gas distribution passages of the fuel cell stack. The first plates each further include a flow path carrying gases from at least one of the gas manifold holes to the flow field of the first plate. The flow path is formed at least in part by channels on the second side of an adjacent second plate when the plate assemblies are stacked together.
