SEPARATOR FOR FUEL CELL AND MOLDING MATERIAL THEREFOR

摘要

A molding material from which a separator for fuel cell capable of exerting excellent mechanical and electrical properties can be obtained. This molding material is an aggregate of granular composite materials (25) each comprising graphite powder (21) coated with coating layer (24) composed of phenolic resin (22) and carbon nanofiber (23). The composition thereof is composed of 55 to 91 mass% of graphite powder, 9 to 25 mass% of phenolic resin and 3 to 30 wt.% of carbon nanofiber.
