Abstract

Disclosed is an integrated fluorine gasket manufactured by injection molding for hydrogen fuel cells. In particular, a fluorine compound having a fluorine content of about 60 to 75 parts by weight based on 100 parts by weight of a fluoroelastomer is disposed in a gasket. The resulting fluorine gasket is integrated with a thin bipolar plate having a thickness of about 200 μm or less to have a thickness of about 750 μm or less by injection molding on the thin bipolar plate and by cross-linking.
