<P>PROBLEM TO BE SOLVED: To provide a separator for a polymer electrolyte fuel cell with light weight, low volume resistance, and high corrosion resistance, which can be manufactured at low cost. <P>SOLUTION: The separator for the polymer electrolyte fuel cell is made of a conductive resin composition containing polymethylpentene by 6 to 11 mass% and graphite powder by 89 to 94 mass%. The separator is manufactured by preparing the conductive resin composition containing polymethylpentene by 6 to 11 mass% and graphite powder by 89 to 94 mass% by mixing the polymethylpentene and the graphite powder, primarily molding the conductive resin composition into a small pellet shape or small chip shape, filling the primarily molded bodies in a mold having groove-shaped parts, and by secondarily molding them for 1 to 15 minutes with a temperature of 200 to 300°C and a pressure of 30 to 50 Mpa. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
