Abstract
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.
