The embodiment of the invention provides a graphite molded bipolar plate and a preparation method thereof, and the preparation method comprises the following steps: S01, uniformly mixing graphite powder and resin powder according to a mass ratio of (1-9): 1 to obtain mixed powder; the mixed powder is placed in a mold for mold pressing, and a mold pressing polar plate is obtained; and S02, curing the molded polar plate in the step S01 to obtain the graphite molded bipolar plate. The invention also provides the graphite molded bipolar plate prepared by the preparation method. According to the preparation method, the curing time of the molded polar plate can be effectively shortened, so that the preparation period of the graphite molded bipolar plate can be effectively shortened, and the prepared graphite molded bipolar plate is not easy to deform and has relatively good deformation resistance. The preparation method disclosed by the invention is simple, the prepared bipolar plate is integrated and thin, has goo
