    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 is to provide an apparatus to manufacture joined laminated media and a method therefor. The joined laminated media that are manufactured from the membrane materials and that are joined by being pressed have no displacement, deformation of the membrane materials, or any defect in joining the boundary faces of the laminated materials, and are efficiently manufactured in a good yield. The apparatus can manufacture a joined laminated-media where the laminated media are placed in the housing space (S) that is formed by a pair of endless belts (15a, 15b) and the sealing member (24). The laminated media are then transported in a state where the laminated media are fixed by the pair of endless belts (15a, 15b) that are closely attached to the laminated media because the air is discharged from the housing space (S) through the discharge holes (17) and they are joined by being pressed in the hot-press section (11) and cold-press section (13).

    摘要： A seal and corresponding method of manufacture of stacks enabled by the physical properties of the seal are provided. In the instance of a fuel cell or other electrochemical stack, the seal provides low-cost manufacturing and reliable/durable operation in high temperature (e.g., 120° C. to 250° C.) and acidic environments. The seal provides an elastomeric material characteristic providing resiliency and flexibility, and a protective characteristic that protects the seal from the high temperature acidic environment, such as found in high temperature PEM fuel cells. The seal is affixed to a plate of a fuel cell stack assembly prior to assembly of the stack, such that there is no requirement to apply an adhesive seal, gasket, free flow to solid sealing material, or the like, to each plate during assembly of the fuel cell stack, or during a disassembly and re-assembly process.
