PROBLEM TO BE SOLVED: To avoid leakage of gas and cooling water and to reduce the yield by manufacturing in few man-hours. SOLUTION: This manufacturing method of a separator for a solid polymer fuel cell is characterized in having a process of disposing a core 25 sublimated or molten by heat treatment in a mold 23 formed of a cope 21 and a drag 22, a process of injecting a mixture formed by mixing, at least, graphitization retardant resin with carbon powder in the mold 23 and molding a separator- shaped compact 27, and a process of carbonizing the graphitization retardant resin in the compact by the heat treatment, sublimating or melting the core, and forming the separator 27 having a hollow part 26 on its inside. |
