摘要： Solid polymer electrolyte fuel cell stacks require a significant nominal compressive loading for proper operation and sealing. This loading is typically provided using relatively thick end plates and tight straps. In certain fuel cell applications, one or more solid polymer electrolyte fuel cell stacks are secured in larger enclosures (e.g. for isolation and crashworthiness in automotive applications). The enclosures however can themselves be sturdy enough to provide the necessary loading on the fuel cell stacks within. The present invention takes advantage of that to allow for use of thinner end plates and/or weaker straps which would otherwise be insufficient for use.

摘要： A method for creating a formed-in-place seal on a fuel cell plate is disclosed. The method includes first dispensing a flowable seal material along a first sealing area of a fuel cell plate requiring the seal material. Next, a preformed template is located adjacent to at least a portion of the fuel cell plate, the template including predetermined apertures corresponding with a second sealing area of the plate, such that the apertures are coextensive with at least a portion of the first sealing area. Flowable seal material is applied into the apertures, and is then cured to a non-flowable state.
