FUEL CELL BIPOLAR PLATE AND PREPARATION METHOD

The present disclosure provides a fuel cell bipolar plate and a preparation method. The method includes: synchronously performing cathode flow field pre-rolling and anode flow field pre-rolling on both surfaces of a pair of flexible graphite coils; synchronously performing cathode flow field secondary rolling and anode flow field secondary rolling on both surfaces of the pre-rolled flexible graphite coils; cutting oxidant inlets/outlets, fuel inlets/outlets, and coolant inlets/outlets in the flexible graphite coils after secondary rolling, and cutting the flexible graphite coils into a bipolar plate shape to obtain a cathode plate and an anode plate; performing resin impregnating, cleaning, and curing on the cathode plate and the anode plate; oppositely arranging and bonding the cathode plate and the anode plate to form a fuel cell bipolar plate; synchronously fitting a cathode stiffener and an anode stiffener to obtain a finished fuel cell bipolar plate.
