Abstract
A fuel cell separator obtained by molding a composition containing graphite powder and an epoxy resin component containing a main agent, a curing agent, and a curing accelerator, in which the average particle diameter d50 of the graphite powder is 20 to 80 μm, and the average height of the graphite powder measured using a laser microscope is 30 to 70% of the average particle diameter d50, has good bending strength and bending fatigue characteristics even in an environment of 70° C.
