Abstract
A plate includes a working face and a header portion. The working face defines a plurality of reactant channels thereon. The header portion is disposed in a peripheral area of the plate and includes a plurality of flanges and a plurality of beads. The flanges are disposed on the header portion and define a plurality of apertures through the plate. Each flange defines a respective one of the apertures. At least one of the apertures is fluidly connected to the reactant channels. The plurality of beads is disposed on the working face. Each bead is disposed about a respective one of the apertures and thereby defines a respective one of the flanges. Each bead defines a shape consisting of bead-corners and bead-sides. Each bead has a sealing surface thereon. The sealing surface is configured to deflect when exposed to a contact pressure to thereby provide a substantially fluid-tight seal.
