A method for attaching a gasket to a non-gasketed bipolar plate for a PEM fuel cell, including the steps of making a pattern of the gasket; preparing the bipolar plate surface; priming the bipolar plate surface for adhesive according to the gasket pattern; aging the primer coat; screen-printing an adhesive coat onto the primer according to the gasket pattern; positioning the gasket face-down in a mirror-image fixture having channels in the form of the gasket; positioning the bipolar plate face down onto the fixture and gasket; applying pressure to the plate to adhere the gasket thereto in the adhesive-coated areas; removing the plate and gasket subassembly from the fixture; and curing the adhesive to provide a gasketed bipolar plate.
