<P>PROBLEM TO BE SOLVED: To provide a separator and its manufacturing device, wherein warping or waviness of the whole separator does not occur, and which can be applied to a solid polymer fuel cell of low cost and high endurance type. <P>SOLUTION: This separator for the solid polymer fuel cell has a flat part in the periphery, and has a convex part and a recess where the center part is a gas path. Then, this separator has the convex part or the recess around the center part via the flat part. Furthermore, in the manufacturing device of the separator for the solid polymer fuel cell, the concavo-convex working analogous to the shape of the convex part and the recess of the separator is applied to the center section front surface, and around the center section front surface to which that concavo-convex working is applied, this separator has a pair of top and bottom press rolls in which a flat part for carrying out rolling of the workpiece is installed. <P>COPYRIGHT: (C)2004,JPO |
