    摘要： The present invention provides a composite separator for a polymer electrolyte membrane fuel cell (PEMFC) and a method for manufacturing the same, in which a graphite foil prepared by compressing expanded graphite is stacked on a carbon fiber-reinforced composite prepreg or a mixed solution prepared by mixing graphite flake and powder with a resin solvent is applied to the cured composite prepreg such that a graphite layer is integrally molded on the outermost end of the separator.For this purpose, the present invention provides a method for manufacturing a composite separator for a polymer electrolyte membrane fuel cell, the method including: preparing a prepreg as a continuous carbon fiber-reinforced composite and a graphite foil; allowing the cut prepreg and graphite foil to pass through a stacking/compression roller to be compressed; allowing the prepreg in which the graphite foil is integrally stacked to be heated and pressed by a hot press such that hydrogen, air, and coolant flow fields are formed or to pass through a hot roller to be formed into a separator; removing unnecessary portions from the heated and pressed separator using a trim cutter; and post-curing the thus formed separator, wherein the graphite foil may be stacked on the prepreg as the continuous carbon fiber-reinforced composite such that a graphite layer is integrally formed with the prepreg.

    摘要： The present invention provides a method for manufacturing a composite separator for a fuel cell, which can reduce the electrical contact resistance by performing an additional post-treatment to remove residual resin remaining on the surface of the composite separator by plasma etching. In certain preferred embodiments, the present invention provides a method for manufacturing a composite separator for a fuel cell, in which a liquid phase resin for gasket is applied to the surface of the composite separator along a predetermined gasket pattern, or a semi-cured resin for gasket in the form of a film with a predetermined gasket pattern is stacked on the surface of the composite separator, and then plasma etching is performed to remove the residual resin and, at the same time, cure the resin for gasket, thus reducing the overall processing time to improve the productivity and preventing a composite material of the separator from being damaged.
