Patent number: 8921008Abstract: 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.Type: GrantFiled: January 18, 2011Date of Patent: December 30, 2014Assignees: Kia Motors Corporation, Hyundai Motor CompanyInventors: Sae Hoon Kim, Sang Mun Chin, Seong Il Heo, Suk Min Baeck, Yoo Chang Yang
