description The invention discloses a flexible composite bipolar plate which comprises conductive carbon cloth, the outer side of the conductive carbon cloth is coated with conductive filler, the flexible composite bipolar plate is formed through hot press molding, and the invention further discloses a preparation method of the flexible composite bipolar plate. The framework is filled with the conductive filler, the bipolar plate with good flexibility and strength is formed, the conductivity and the mechanical property are better, meanwhile, after the carbon cloth and the conductive filler are subjected to hot pressing, the integrated bipolar plate is formed, the layering phenomenon is avoided, in the preparation process of the bipolar plate, the conductive filler is coated in a melting mode and is subjected to hot pressing in the carbon cloth, an organic solvent is not used, and the cost is low. The process is simple and environment-friendly. 本发明公开了一种柔性复合双极板，包括导电碳布，导电碳布外侧涂覆有导电填料，通过热压成型，形成柔性复合双极板，还公开了该柔性复合双极板的制备方法，本发明适用于
