A polymer composite bipolar plate for a polymer electrolyte membrane fuel cell (PEMFC) is prepared as follows: (a) compounding phenolic resin and carbon fillers to form bulk molding compound (BMC) material, the BMC material containing 60 to 80 wt% graphite powder, 1 to 10 wt% carbon fiber; and one ore more conductive carbon fillers selected from: 5 to 30 wt% Ni-planted graphite powder, 2 to 8 wt% Ni-planted carbon fiber and 0.01 to 0.3 wt% carbon nanotubes, based on the weight of the phenolic resin, provided that the sum of the amounts of the carbon fiber and Ni-planted carbon fiber is not greater than 10 wt%; (b) molding the BMC material from step a) to form a bipolar plates having a desired shape at 80-200 DEG C and 500-4000 psi.
