  • Publication number: 20100025879
    Abstract: A highly filled composite is formed by extruding through a multiple screw extruder a thermoplastic resin and sufficient filler so that an autogranulating extrudate exits the extruder barrel. The extruder is operated without an exit manifold, strand die or breaker plate. The extrudate forms irregularly shaped granules. The granules provide a molding composition that can be used to form highly filled molded articles such as fuel cell separator plates and end plates by compression, injection or compression-injection molding.

  • Patent number: 7297428
    Abstract: A registration arrangement for a fuel cell stack assembly incorporates registration posts and registration apertures or recesses. Fuel cell assemblies of the stack may include first and second flow field plates and a membrane electrode assembly (MEA) having an active area. Registration apertures are defined in each of the MEA and the first and second flow field plates. The respective registration apertures are situated within non-active areas of the MEA when the first and second flow field plates and the MEA are in axial alignment. Registration posts are configured for reception within the registration apertures. Each of the registration posts has an outer surface differing in shape from a shape of the inner surface of the registration apertures. The inner surface of the registration apertures contact the outer surface of the registration posts at a plurality of discrete press-fit locations.
