Abstract:
A fluid cell component comprising, in combination, : (i) a fluid flow field plate for use in a fuel cell in the form of a single unitary resin impregnated flexible graphite sheet having opposite planar outer surfaces, said flexible graphite sheet having embedded therein a dispersion of a plurality of needle-shaped ceramic fiber particles which are non-reactive with flexible graphite and stable at temperatures up to 2000.degree. F., said needle-shaped particles extending into said graphite sheet from at least one of said planar outer surfaces to provide channels for containing said resin, one of said planar outer surfaces being flat and other of said planar outer surfaces having formed therein a continuous fluid flow channel adapted to receive and exhaust a fluid fuel or oxidant; and (ii) a thin flat flexible graphite sheet arranged contiguous and coextensive with said flat planar outer surface of the fluid flow field plate and being bonded thereto by thermoset pockets of resin.
