<P>PROBLEM TO BE SOLVED: To provide a warpage correcting method for effectively correcting warpage of a fuel cell separator. <P>SOLUTION: In the method of correcting warpage of the fuel cell separator consisting of (1) a process of pinching a plurality of the fuel cell separators made of a composition including a conductive material and thermosetting resin with a pair of correcting plates, (2) a process of giving it a prescribed load, (3) a process of heating the separators together with the correcting plates by putting them into a furnace, and (4) a process of taking them out of the furnace, cooling them down to a prescribed temperature and then releasing the prescribed load, heating temperature at the process (3) is set higher than glass transition temperature of a composition molding and lower than pyrolysis starting temperature. With this, the warpage of the fuel cell separator is corrected. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
