摘要:
A graphite-vinyl ester resin composite conducting plate is prepared in the present invention. The conducting plate can be used as a bipolar plate for a fuel cell, counter electrode for dye-sensitized solar cell and electrode of vanadium redox battery. The conducting plate is prepared as follows: a) compounding vinyl ester resin and graphite powder to form a bulk molding compound (BMC) material, the graphite powder content ranging from 70 wt % to 95 wt % based on the total weight of the graphite powder and vinyl ester, wherein 0.01-15 wt % functionalized graphene, based on the weight of the vinyl ester resin, are added during the compounding; b) molding the BMC material from step a) to form a conducting plate having a desired shaped at 80-250° C. and 500-4000 psi.
