MANUFACTURING METHOD OF FUEL CELL SEPARATOR, MANUFACTURING METHOD OF INTERMEDIATE MOLDING AND INTERMEDIATE MOLDING

摘要

PROBLEM TO BE SOLVED: To achieve mass production of a mold of excellent quality performance such as inner-face uniformity for a fuel cell separator of thin shape and high accuracy. SOLUTION: The manufacturing method of the fuel cell separator for manufacturing fuel cell separators by heating/pressure molding carbonaceous powder and a binder consists of an intermediate molding manufacturing process in which raw material pulverulent product containing carbonaceous powder and a binder is cast in (a step 113), a preliminary molding is made (a step 114), and a given intermediate molding is made, as well as a manufacturing process of arranging the intermediate product thus made in a molding die (a step 123), continuously heating the intermediate molding arranged in the molding die in a furnace (a step 131), and pressure molding (a step 133).
