  • Patent number: 9472815
    Abstract: A separator for a fuel cell and a method for manufacturing the same comprise two sheets of metal plates integrally formed to minimize contact resistance between an upper metal plate and a lower metal plate. The method for manufacturing the separator includes steps of preparing an upper metal plate and a lower metal plate, each plate having opposing main sides, and applying a coating liquid containing a polymer composite material on both sides of the upper and lower metal plates, to form first and second composite material layers on both sides of the upper plates and third and fourth composite material layers on both sides of the lower plates. The method further includes stacking the upper metal plate on the lower metal plate, before drying the respective composite material layers, and integrally bonding the second composite material layer and the third composite material layer to form a single intermediate composite material layer.

  • Patent number: 8945792
    Abstract: A separator for a fuel cell includes a metal plate which defines a passage and a manifold, frames having gaskets which are integrated therewith using injection, and a bonding unit for bonding the frames to the metal plate. The gaskets may be differently formed. This resolves process interference problems between conductive surface treatment and gasket cross-linking, obviates deburring of the gasket, and preventes poor injection of the gaskets, which ensures stable quality of the separator, increases productivity and decreases the manufacturing cost.

  • Patent number: 8921008
    Abstract: The present invention provides a fuel cell separator with a gasket and a method for manufacturing the same, which can prevent corrosion of the separator and improve corrosion resistance of the separator. In particular, the present invention provides a fuel cell separator with a gasket and a method for manufacturing the same, in which an adhesive is coated on the entire or partial surface of the separator, preferably by screen printing. A process of integrally molding a gasket to the separator is then performed such that the edges of the separator are not exposed to the outside after the injection molding process but, rather, are coated with the resin adhesive. The present invention thereby prevents corrosion of the separator, improves corrosion resistance of the separator, and prevents formation of burrs during the injection molding process.
