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.

Uniform graphite plate

An electrically conductive seal for bonding together individual electrical fuel cells into an assembly in the form of a stack in which the individual electrical fuel cells are electrically connected together by the electrically conductive seal.
