ABSTRACT:
A bipolar plate is provided which is constructed of a composite material including at least thirty percent carbon and up to seventy percent of a flowable resin. The material is flowed into a mold and hardened, preferably by heat or catalyst, to form the bipolar plate. The resin is preferably a polyester resin which, along with the carbon, can function effectively within a bipolar plate of a fuel cell. A method for forming bipolar plates from a composite material including carbon and a flowable resin, by flowing the material into a mold, is also provided. Specific compositions for the composite material are also provided.
