<P>PROBLEM TO BE SOLVED: To provide a separator for a fuel cell and a manufacturing method wherein a surface does not become excessively abundant with a resin even after a blast treatment work on the surface has been applied and the contact resistance can be reduced. <P>SOLUTION: (1) The separator for the fuel cell in which conductive minute particles 1 are adhered or made to be thrusted by a shot blast into the resin of a contact part of the surface of the separator with a diffusion layer and a contact part of the surface of the separator with a separator of an adjoining cell. (2) The manufacturing method of the separator for the fuel cell having a first process in which the conductive minute particles are adhered to or made to be thrusted into the resin 2 by a shot blast at a part of the surface of the separator where the contact resistance is required to be low. (3) It has a second process in which manufacturing of a reaction gas flow passage is carried out by the shot blast and a surface treatment work is carried out, and working of cooling water flow passage is carried out by the shot blast and the surface treatment work is carried out. (4) The resin 2 is a thermoplastics. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
