A hybrid bipolar plate assembly comprises a metallic anode plate, a polymeric composite cathode plate, and a metal layer positioned between the metallic anode plate and the composite cathode plate. The metallic anode and composite cathode plates can further comprise an adhesive sealant applied around the outer perimeter to prevent leaking of coolant. The assembly can be incorporated into a device comprising a fuel cell. Further, the device can define structure defining a vehicle powered by the fuel cell.
