  • In-Situ Molding Of Fuel Cell Separator Plate Reinforcement
    Publication number: 20080116609
    Abstract: A method for making a reinforced composite separator plate is disclosed. According to the method, a reinforcement media (16) is molded into a composite material (22, 24) such as graphite embedded in a thermoplastic or thermosetting polymer resin matrix. The composite material is placed in a mold cavity (15, 17) such that the composite material flows through the reinforcement media. The separator plate is molded into a net step. The molding is performed via injection or compression moulding, or a combination of both.
