The invention belongs to the technical field of a fuel cell, and discloses a conductive anti-corrosive coating process for an aluminium flow field plate. The conductive anti-corrosive coating process comprises the steps of firstly, carrying out preprocessing of polishing, precision polishing, ultrasonic cleaning, alkali cleaning, washing and the like on the aluminium flow field plate; then placing the preprocessed aluminium flow field plate into aqueous solution of graphene oxide, which contains tetrahydroxy aluminate ions, to impregnate, and after impregnation, cleaning with deionized water and carrying out normal temperature drying; and then impregnating in sodium hypophosphite solution to carry out processing, and after processing, cleaning with the deionized water and carrying out normal temperature drying. According to the invention, one compact graphene coating is coated on the surface of the aluminium flow field plate by adopting a chemical impregnation method which is simple to operate, low in cost, green and environmental-friendly. Conductivity and corrosion resistance testing results show that compared to an uncoated aluminium flow field plate, the coated aluminium flow field plate is obviously improved in corrosion resistance and is not reduced in conductivity, and thus, the requirements of the aluminium flow field plate for high corrosion resistance, high conductivity and low contact resistance in a fuel cell environment can be met.
