A kind of preparation method of pre-coating on stainless steel strip for preparing fuel cell bipolar plate |
| abstract |
A method for preparing a precoat on a stainless steel strip for preparing a fuel cell bipolar plate, comprising surface treatment of the stainless steel strip and precoating on the surface of the stainless steel strip. The surface treatment of the stainless steel strip is to polish the surface of the stainless steel strip to a certain roughness , and then remove the passivation film; coating pre-coating includes coating slurry preparation and coating coating. Colloidal coating slurry, coating coating is to apply the prepared coating slurry to the surface of the stainless steel strip, and then attach a polytetrafluoroethylene film to the surface of the coating. After hot pressing, the polytetrafluoroethylene film is stripped. The beneficial effects of the invention are that the materials and equipment are simple and the cost is low. The surface of the bipolar plate is not corroded. No cracks are formed during the molding of the flow field. The coating has a long service life. Battery stability is improved. |
