Title:
COLD-PRESSING METHOD FOR BIPOLAR PLATE MANUFACTURING
Document Type and Number:
WIPO Patent Application WO2003049212
Kind Code:
A3
Abstract:
A method for producing a graphite bipolar separator plate for a polymer electrolyte membrane fuel cell in which a powder mixture having at least one graphite component and at least one resin is placed into a plate mold and pressed at substantially ambient temperature, resulting in formation of cold-pressed plate. The cold-pressed plate is heated to a temperature suitable for curing the cold-pressed plate, resulting in formation of the graphite bipolar separator plate.
