Abstract
An illustrative method of making a fuel cell component includes obtaining at least one blank plate including graphite and a polymer; establishing a temperature of the blank that is sufficient to maintain the polymer in an at least partially molten state; and applying a compression molding force to the blank until the polymer is essentially solidified to form a plate including a plurality of channels on at least one side of the plate. The blank plate has a central area having a first thickness. The blank plate also has two generally parallel edges on opposite sides of the central area. The edges have a second thickness that is greater than the first thickness.
