PURPOSE: A method for preparing a bipolar plate using an electrically conductive resin composition is provided, wherein the bipolar plate shows excellent electrical conductivity, thermal conductivity and formability. CONSTITUTION: The method comprises the steps of extrusion mixing 10-95 wt% of a thermoplastic resin and 5-90 wt% of an electrically conductive material with an electrical conductivity of 10¬-2 ¥Ø/cm2 or less at a barrel temperature of 200-340 deg.C to prepare a thermoplastic resin composition; and preparing a bipolar plate using the resin composition, or further electroplating, evaporation-depositing or coating a metal material onto the prepared bipolar plate. Preferably the composition comprises further 5-40 wt% of at least filler selected from the group consisting of glass fiber; an inorganic filler comprising mica, talc and wollastonite; and a halogenated or nonhalogenated flame retardant. |
