<p><P>PROBLEM TO BE SOLVED: To provide a separator for fuel cell that can be made thin while maintaining gas seal performance, conductivity, and mechanical strength, and has a high precision of thickness with high reliability, its manufacturing method, and a fuel cell using the same. <P>SOLUTION: The separator for fuel cell 1 is molded of a forming material containing a conductive granule and a thermoplastic resin. The surface of the separator is rich in conductive granule, and the content of the conductive granule changes in a manner of continuously or gradually slanting from the surface toward inside. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
