Abstract
A fuel cell separator made of conductive material and resin wherein the conducive material is recycled from waste of fuel cell separators. The fuel cell separator consisting of conductive material and resin is made by using the waste of fuel cell separator consisting of conductive material and resin. The waste of fuel cell separator is pulverized to powder and is mixed with unused resin and, if necessary, supplemental conductive material, to establish powdered material. The powdered material is molded under the predetermined molding pressure and temperature. The fuel cell separators using the recycled material are comparable to fuel cell separators made solely from new material. In another aspect, a method of producing a fuel cell separator using the recycled material is disclosed.
