NOVELTY - Producing isotropic, electrically conductive composite composition involves: (a) continuously supplying compressible mixture comprising exfoliated graphite worms and a binder or matrix material (3-60 wt.%); (b) continuously compressing the compressible mixture at a pressure of 5-50000 psi or 0.035-350 MPa in a first direction into a cohered graphite composite compact; and (c) continuously compressing the composite compact in a second direction, different from the first direction, to form the composite composition in a sheet or plate form.    USE - For producing isotropic, electrically conductive composite composition (claimed), useful for making fuel cell bipolar plates or flow field plates.    ADVANTAGE - The composite composition is manufactured using a fast, continuous, and cost-effective process, which can be automated and adapted for mass production. The starting materials are relatively inexpensive graphite-based materials, and no expensive and tedious process such as chemical vapor infiltration is required. The resulting bipolar plate or flow field plate is of low cost, excellent structural integrity and is not subject to the delamination problem commonly associated with multi-layer composites induced by the mis-match in coefficients of thermal expansion and elastic constant. The bipolar plate exhibits excellent electrical conductivity that exceeds the target bipolar plate conductivity value set forth by the US department of energy for automotive fuel cell applications. The bipolar plate exhibits high thickness-direction electrical conductivity. The composition can also be made into a precursor form (without the final shaping operation) for easy storing, shipping, and handling operations. The resin-bonded exfoliated graphite composition can be stored in a refrigerator, thus preventing the resin curing reaction from advancing to an undesired extent and thus the composition can have a long storage life. The end-user can simply cut the composition into individual pieces, which are molded into bipolar plates when and where the plates are needed. Alternatively, in-line embossing or matched-mold molding can be used to directly produce bipolar plates on an essentially continuous basis.
