Technology of Polyphenylene Sulfide (PPS) Resin/Graphite Conductive Composite for Bipolar Plate

Abstract:

A kind of conductive composite material for the bipolar plate of proton-exchange membrane fuel cells (PEMFC) was fabricated by the hot-pressure molding with graphite powders and polyphenylene sulfide (PPS) resin powders. The influencing factors including PPS resin content, molding pressure and molding temperature, and temperature holding time on the conductivity, flexural strength and density of the composite were investigated. It was found that the perfect conditions for the fabrication of bipolar plate were that the PPS resin content was 25%wt, the forming pressure was 20 MPa, the mold temperature was 320°C and the holding time was 25 min.
