The hydrogen-oxygen fuel cell is used as an energy conversion device mainly based on green energy, has high energy conversion rate, and is environment-friendly and pollution-free. However, the pem fuel cell may undergo complicated cycle processes of fuel supply, humidity, temperature, current, voltage, etc. with actual vehicle condition changes, resulting in accelerated degradation of the electrodes of the fuel cell.
Although the conventional graphene bipolar plate of the hydrogen-oxygen fuel cell has the characteristics of high conductivity, good corrosion performance and the like, the following defects are not suitable for batch production: (1) the brittle substance causes assembly difficulty, and the thickness is not easy to be thinned; (2) generally sintering into porous plate, adding additive; (3) long graphitization time, difficult mechanical processing and high price.
The metal bipolar plate of the hydrogen-oxygen fuel cell has good electric and thermal conductors; the mechanical property is good, and the strength is high; the gas barrier property is good; non-porous, etc., but is susceptible to corrosion and requires surface modification.

Aiming at the problem that the conventional oxyhydrogen fuel cell is extremely easy to wear, the invention provides a preparation method of a metal electrode protective coating of the oxyhydrogen fuel cell, Dopamine (DA) is polymerized on the surface of titanium carbide (MXene) by a wet chemical method to form PDA-Mxene filler, and then the PDA-MXene is introduced into an epoxy resin coating, so that the corrosion resistance of the coating is improved.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for preparing an electrode protective coating for a hydrogen-oxygen fuel cell, comprising the steps of:
step 1, adding 200-500 mg MXene into 100 mL of deionized water, and performing ultrasonic dispersion;
step 2, adding 100-400 mg dopamine hydrochloride into the mixed solution in the step 1, stirring vigorously for 1 h, and adding a Tris-HCl solution to adjust the pH value of the solution to 8-9 during the stirring;
step 3, continuously stirring the system obtained in the step 2 under a dark condition for reacting for 24-48 h;
step 4, centrifugally separating the obtained suspension for 5min at 8000 r/min of 5000-;
and 5, mixing the epoxy resin, the N, N-dimethylformamide and the solid prepared in the step 4 according to the weight ratio of 100 g: 10mL of: 1g of the solid is respectively weighed, the solid and N, N-dimethylformamide are mixed and then ultrasonically dispersed for 10 min, then epoxy resin is added into the system to continue the ultrasonic dispersion for 10 min, then a rubber head dropper is used for sucking the system, 0.4-0.7 g of the mixture is dripped on a steel sheet, and a wire rod is used for uniformly rolling the mixture in the same direction to prepare a coating;
and 6, drying the prepared coating in a drying oven at the temperature of 80-100 ℃ for 20 min.
Aiming at the problem that the conventional oxyhydrogen fuel cell is easy to lose electricity, the invention provides an electrode protective coating of the oxyhydrogen fuel cell, which is prepared by taking epoxy resin base resin and PDA-MXene as a filler. The invention self-polymerizes DA on the surface of MXene under the slightly alkaline condition to obtain MXene-PDA, and then coats the MXene-PDA as a filler on a 304 stainless steel bipolar plate in combination with epoxy resin.
The invention has the beneficial effects that: (1) the high specific surface area and wide adhesion of MXene allow PDA to adhere to the surface of MXene as much as possible, and the blocking effect of MXene is enhanced; (2) the secondary reactivity of PDA can be corroded instead of MXene, enhancing corrosion protection.
