PROBLEM TO BE SOLVED: To provide a separator for highly efficient fuel cells that can perform uniform gas supply easily to a whole electrode, and can lessen contact resistance with the electrode. SOLUTION: The separator for fuel cells has a carbon structure body formed including a porous carbon film structure body which has fine continuous porous- ness, a perforation rate of 50 to 85%, and a rate of surface opening smaller than the perforation rate, and including a precise carbon film structure body. And the separator for fuel cells that is constituted so that the above porous film structure body may bear a flow delivering function, can perform uniform gas supply easily to the whole electrode, and can lessen the contact resistance by making it a face contacting. |
