The invention relates to the technical field of fuel cell functional coating, in particular to a superconducting and super corrosion resistant functional coating of a fuel cell metal bipolar plate and a preparation method thereof. The superconducting and super corrosion resistant functional coating of the fuel cell metal bipolar plate comprises a self-healing layer, a super corrosion resistant layer and a selectively deposited superconducting layer. The premise of the superconducting and super corrosion resistant functional coating of the fuel cell metal bipolar plate is enhancing the service life of the fuel cell metal polar plate. The superconducting and super corrosion resistant functional coating material of the fuel cell metal bipolar plate disclosed by the invention has the capability of filling the pinholes automatically during use, therefore, a recycle multilayer structure to avoid the pinholes is not required to design; meanwhile, the coating has the super corrosion resistant and the superconducting compositions, therefore, the lower contact resistance and corrosion current density compared with the prior art can be achieved without adding noble metals, and the processing cost of the metal plate is greatly reduced.
