(57) [Problem] To provide a separator having a uniform shape and a predetermined shape while securing good conductivity by reducing the amount of resin. SOLUTION: 85-97% of graphite powder, thermosetting resin 3 Using a bond carbon set to a composition ratio of １５15%, a mold is filled with a preform obtained by cold-forming the compound directly or in advance into a shape close to the final shape, 150 to 1500 kgf / cm 2 , preferably 300 A molding surface pressure in the range of １０００1000 kgf / cm 2 is applied to form a separator having a predetermined shape. |
