PROBLEM TO BE SOLVED: To provide a fuel cell separator molded of a composition containing mainly graphite, an epoxy resin, a curing agent and an accelerator, while adding the 15 parts or less by mass of epoxy resin to the 100 parts by mass of graphite, and its production method. SOLUTION: The need for mechanical machining after molding is eliminated, the conductivity and mechanical strength of a product is improved at a significant level, superior separativeness and dimensional precision in molding are provided and higher performance, less proportion defectives and lower cost are given to the product. |
