Preparation of CF Reinforced PPS/Graphite Conductive Composite for Bipolar Plate
Abstract:
A kind of carbon fiber (CF) reinforced conductive composite material with graphite powders and polyphenylene sulfide (PPS) resin powders were fabricated by the hot-pressure molding method. The influence of graphite content and CF addition on the conductivity, flexural strength and density of the composite were investigated. Took into account the performance requirement of the bipolar plate of PEMFC and economic aspect, the suitable conditions for the fabrication of bipolar plate were found: the proportion of graphite and PPS was 75/25 and the addition of CF was 2.5%(wt).
