摘要： Fuel cell separators having on one side or both sides thereof channels for gas supply and discharge, which channels are formed from compositions composed mainly of thermosetting resin and graphite particles. The compositions are designed to have a flexural modulus of at most 20 GPa and a flexural strength of at least 50 MPa (both measured according to JIS K6911). Also disclosed is a solid polymer type fuel cell system in which part or all of its separators are fuel cell separators as defined above. Due to its high strength and low flexural modulus, the fuel cell separators of the invention do not break as a result of deformation at the time of fuel cell assembly. Moreover, the fuel cell separators of the invention absorb shocks and vibration imparted to the fuel cell system. Therefore, they is useful for automobile fuel cells which are normally subject to vibrations and shocks during operation.

摘要： A mold for producing a fuel cell separator with which a flash, even if it occurs, does not cause a thickness unevenness. The mold includes a plurality of molds 2, 4 and 10, and a fuel cell molding cavity 5 for separator being defined among the molds. At least one of the molds is provided with a flash reservoir cavity 11 which is communicated with the cavity 5. An amount of material in excess of the volume of the cavity 5 is charged, and melted by the application of pressure and heat. The melted material fills up the entire cavity 5, with the excess thereof entering the cavity 11. Since the molds 2 and 10 maintain a direct contact with each other, it is possible to obtain a separator molded with a high accuracy.

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.
