Abstract
The present invention provides a fuel cell separator having an airtight gasket, in which a gasket is integrally injection-molded in a region that requires airtightness of a fuel cell separator to maintain airtightness of each flow field of the separator and to smoothly guide the fluid flow in each flow field. For this purpose, the present invention provides a fuel cell separator having an airtight gasket, which is integrally injection-molded on both surfaces of the separator to form a closed curve.
