HYBRID SEAL APPLICATION PROCESS

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.

主权项

1. A plate for a fuel cell comprising:
a plate with a first surface, a second surface, and a plurality of header openings formed therein; a flow field formed on the first surface of the plate, the flow field including an inlet feed region and an outlet region, the inlet feed region and the outlet region having feed area channels in fluid communication with at least one header opening, the feed area channels defining three dimensional surface features; and at least one sealing member formed on the plate, the sealing member including at least one substantially linear section interlacing with at least one substantially non-linear section.
