Provided is a method for producing a fuel cell separator, comprising: a step for producing a premolding sheet for forming a delicate part by subjecting a molding material for a delicate part, which contains a carbonaceous powder and a thermosetting resin binder, to pressure molding under a temperature that is the softening temperature of the thermosetting resin binder or higher, but lower than the hardening temperature of the thermosetting resin binder; a step for producing a powder for forming a porous part, which contains a carbonaceous powder and a thermosetting resin binder; a step for filling the premolding sheet for forming a delicate part and the powder for forming a porous part in a mold which has an uneven molding surface corresponding to the shape of the gas flow path, such that the uneven molding surface and the powder for forming a porous part oppose each other; and a step for subjecting the premolding sheet for forming a delicate part and the powder for forming a porous part to molding by applying heat and pressure to the mold under a temperature that is at least the highest setting temperature from among the setting temperatures of the aforementioned plurality of thermosetting resin binders. |
