<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a conductive substance-contained stainless steel separator which can increase the contact area of the conductive substance with respect to a membrane electrode assembly. <P>SOLUTION: The manufacturing method of a conductive substance-contained stainless steel separator consists of a preparation process for preparing a stainless steel material 22 in which granular conductive substance 21... is contained in a stainless steel matrix 27; a rolling process in which the stainless steel material 22 is rolled out in a prescribed thickness and the rolled material 23 is obtained; a surface removal process for removing the surface 34 of the rolled material 23; a flattening process, in which by grinding the surface where the surface 34 is removed; the surface 27a of the stainless steel matrix 27 and the exposed face 21b... of the conductive substance 21... are made flat; and a melting process, in which a solvent 48 is applied on the flat ground surface 47 obtained and while maintaining the conductive substance 21..., in a state of non-melting, the stainless steel matrix 27 is melted by this solvent 48. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
