Abstract:
1. A fuel cell separator which consists of a complex that is configured by bonding graphite powder by means of a thermosetting resin, and in which ribs for forming fuel gas passages and oxidant gas passages on a surface of said separator, and coolant water passages and fuel gas and oxidant gas manifolds in a peripheral area of said separators are formed by a resin molding method, wherein said ribs are formed in a shape and pattern such that said fuel gas passages and said oxidant gas passages extend both horizontally and vertically, plural flattened graphite particles are exposed from top surfaces of said ribs for forming passages and functioning as a contact surface with an electrode, and a resin defective portion is formed between respective adjacent ones of said plural exposed flat graphite particles.
