  • Patent number: 9806353
    Abstract: The present invention provides a fuel cell separator with a gasket manufactured by integrally forming a gasket on one side of a separator; independently injection molding a frame gasket on a frame such that a first airtight portion covers the entire surface of the frame to maintain the shape of the frame gasket and a second airtight portion projects upward and downward from both ends of the first airtight portion; and bringing the first airtight portion of the frame gasket into contact with the other side of the separator with the gasket formed on one side thereof. To create a fuel cell stack in certain embodiments, the invention stacks the second airtight portion of the frame gasket on another second airtight portion of an adjacent unit cell with a membrane-electrode assembly interposed therebetween.

  • 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.
