ABSTRACT:
A fuel cell separator plate comprising a portion in contact with an electrode, and a sealing portion provided around the contact portion, the contact portion having a larger surface roughness (Rmax) than that of the sealing portion. It is preferably a molded separator plate made of a composite carbon material comprising carbon and a thermosetting resin.
