Catalyst spraying equipment for fuel cell membrane electrode production

Abstract

The invention discloses catalyst spraying equipment for fuel cell membrane electrode production. The catalyst spraying equipment comprises a box body, an air cylinder, a sliding rail, a first electricheating sheet, a fixing plate, a connecting rod, a turnover mechanical arm, a storage tank, a sealing pipe, a limiting column, an electric nozzle, a supporting plate, a supporting frame, a clamping block, an L-shaped fixing column, a rectangular opening, a guide cylinder, an electromagnetic valve, a vibration plate, a sliding block, an electric push rod, a second electric heating sheet, a ceramicheat conduction column and an ultrasonic vibrator. According to the catalyst spraying equipment, the quantitative repeated spraying and the spraying advancing track are combined with the preheating effect of the second electric heating sheet, so that the coating sprayed after each time of spraying can be rapidly solidified so as to continuously carry out spraying work, the spraying amount of theelectric nozzle is small when the electric nozzle is sprayed each time, the phenomenon that the extremely thin proton exchange membrane is damaged or the swelling phenomenon is caused is avoided, theuniformity and the fineness of spraying can be guaranteed, and the spraying quality is greatly improved while the maximum working efficiency is achieved.

Description

Technical field[0001]The invention relates to the technical field of spraying equipment, in particular to a catalyst spraying equipment for fuel cell membrane electrode production.Background technique[0002]The membrane electrode is generally a combination of proton exchange membrane, catalyst and carbon paper. The proton exchange membrane is usually sandwiched between two carbon papers, and the catalyst can be coated on the outside of the proton exchange membrane or embedded between the carbon paper and the proton exchange membrane. And when the catalyst is coated on the outside of the proton exchange membrane, this places extremely high requirements on the catalyst spraying equipment for the production of fuel cell membrane electrodes.[0003]However, in the existing catalyst spraying equipment for fuel cell membrane electrode production, there are problems of low working efficiency and poor spraying quality. In the spraying process, most of the spraying is a simple trajectory one-ti...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a catalyst spraying equipment for the production of fuel cell membrane electrodes. Combined, the coating after each spraying is cured quickly, so that the spraying work can be carried out continuously and the surface of the coating is not easy to adhere to dust and impurities, and because the spraying amount of the electric nozzle is small in each spraying, it will not be harmful The extremely thin proton exchange membrane causes damage or causes it to swell, and can ensure the uniformity and fineness of the spraying, and greatly improve the spraying quality while achieving the maximum working efficiency
