Abstract
A substrate useful for the formation of, inter alia, a flow field plate for a proton exchange membrane fuel cell, the substrate formed of at least one resin-impregnated sheet of compressed particles of exfoliated graphite comprising two major surfaces, the substrate having an active area with flow field channels thereon, the sheet of compressed particles of exfoliated graphite having a local web thickness in at least about 50% of its active area that is no more than about 55% greater than the minimum web thickness of the active area of the substrate.
