BIPOLAR PLATE FOR FUEL CELL

1. A fuel cell bipolar plate obtained by molding a composition comprising graphite and an epoxy resin composition comprising an o-cresol novolak resin as a base resin, and phenol novolak resin as a curing agent, characterised in that said composition comprises 100 parts by weight of a porous artificial graphite material having a true density of from 1.63 to 2.20 g/ml and an average particle

2020/12/19These plates have high electronic and good thermal conductivity and are stable in the chemical environment inside a fuel cell. Raw bulk graphite is made in a high-temperature sintering process that takes several weeks and leads to shape distortions and the introduction of some porosity in the plates.
