Disclosed herein is a composition suitable for use in the production of a
fuel cell bipolar plate having improved electrical conductivity and
mechanical strength. The composition for a fuel cell bipolar plate can
include about 100 parts by weight of a basic resin composition including
about 10 to about 50 parts by weight of polyphenylene sulfide as a
thermoplastic resin and about 50 to 90 parts by weight of a conductive
filler and about 0.01 to about 30 parts by weight of a disulfide
compound. The composition can improve impregnation of the conductive
filler into the thermoplastic resin.
