TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Material: The conductive additive is ceramics.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The extruder comprises a twin-screw extruder. The cooling station comprises a series of rollers, which directs the extruded polymer/conductive polymer additive composite web along a predetermined path. The series of rollers calenders the extruded polymer/conductive additive composite web such that a desired thickness of the composite web is obtained. The flow channels are formed by laser machining or a hot stamping apparatus.    TECHNOLOGY FOCUS - METALLURGY - Preferred Material: The conductive additive is carbon particles or metal particle. The fiber comprises carbon fibers.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The method further comprises laser machining the polymer/conductive polymer additive composite such that second flow channels are formed into the second surface of the composite. The first flow channels formed into the first surface are equivalent or different to the second flow channels formed into the second surface of the composite. The method further comprises applying a surface treatment to a surface of the polymer/conductive polymer additive composite. Applying the surface treatment comprises applying a surface coating to at least one surface of the polymer/conductive additive composite web. The surface treatment is abrasion resistance coatings, fluoropolymer coatings, conductive coatings, and/or coatings that improve lyophilicity. The surface of the polymer/conductive polymer additive composite web is cross-linked by exposing the surface to UV light, e-beam radiation, and/or gamma radiation. The method further comprises cutting a desired portion of the composite web to form a bipolar plate; packaging the bipolar plate in a container; and grinding up the polymer/conductive polymer additive composite material left behind after the desired portion has been cut out to form composite particles, and recycling the composite particles back into an extruder (102). The method further comprises forming perforations into a surface of the polymer/conductive polymer additive composite web; packaging the bipolar plates in a roll configuration such that individual bipolar plates can be obtained by tearing along one of the perforations; and introducing a fiber into the polymer/conductive polymer additive composite. The continuous polymer/conductive polymer additive composite is formed by introducing polymer and at least one conductive additive into an extruder, and extruding a polymer/conductive polymer additive composite web. The method further comprises directing the extruded polymer/conductive polymer additive composite web to a cooling station (104) where the composite can be cooled to facilitate further processing of the composite. The method further comprises hot stamping the polymer/conductive polymer additive composite such that second flow channels are formed into the second surface of the composite. The composite layers are combined by pressure lamination, heat lamination, and/or adhesive bonding. The method further comprises directing the extruded composites to a lamination roll such that the composite layer are pressure laminated to each other to form a multi-layer structure. Preferred Material: The polymer is poly(tetrafluoroethylene), poly(vinylidenefluoride), polyetheretherketone (PEEK), polyethylene, ultra high molecular weight polyethylene (UHMWPE), polycarbonate, polyolefins (PO), styrene block co-polymers (e.g. Kraton), styrene-butadiene rubber, nylon in the form of polyether block polyamide (PEBA), ethyl vinyl acetate, polyurethane, polypropylene, poly(ethylene terephthalate glycol) poly(vinylchloride) (PVC), and/or polyimides.
