Automatic spraying equipment applied to spe film

Abstract

The invention discloses an automatic spraying device applied to an SPE film and an achieving method of the automatic spraying device. The automatic spraying device comprises a case, a guide rail, a catalyst temperature control spraying device, a motor and a PLC control system. The case is provided with a spraying work platform, a vacuum chamber and an equipment box from top to bottom. The spraying work platform is used for containing a film clamp fixing the SPE film, a sintering porous titanium plate is arranged on the platform top of the spraying work platform, and an induction coil is evenly inlaid in the platform top. The equipment box is internally provided with a vacuum pump and a heating device connected with the induction coil. The guide rail is arranged on the side face of the case. The catalyst temperature control spraying device is in sliding connection with the guide rail and is used for spraying a catalyst to the SPE film. The motor is used for controlling the catalyst temperature control spraying device to move along the guide rail. The PLC control system is connected with the catalyst temperature control spraying device, the motor, the heating device and the vacuum pump at the same time. According to the automatic spraying device, the catalytic performance of the catalyst can be guaranteed, meanwhile, film swelling deformation of the SPE film is avoided, the film forming quality is improved, and the requirement for batched manufacturing is met.

Description

technical field [0001] The invention relates to an automatic spraying equipment applied to SPE film. Background technique [0002] SPE electrolysis is a way to replace the traditional lye electrolyte with a solid polymer electrolyte membrane with proton exchange function. It uses pure water as raw material to produce hydrogen, which is a highly efficient means of hydrogen production with great development prospects in the 21st century. Compared with traditional lye electrolysis, SPE electrolysis has the characteristics of high current density, low cell heat generation, high electrolysis rate, high-purity output (>99.99%) and self-pressurized hydrogen (>0.1Mpa). [0003] In the related technologies of SPE electrolysis, the preparation of SPE membranes loaded with cathode and anode catalysts is an important work. At present, commonly used methods include rotary pressure method and direct spraying method. The working principle of the rotary pressure method is to first c...

AI Technical Summary

Problems solved by technology

[0005] (1) In order to ensure the catalytic performance, the catalyst ink cannot add a large amount of dispersant like the paint, so the catalyst in the catalyst ink will gradually precipitate and agglomerate during the placement of the paint tank, which seriously affects the uniformity of spraying;

[0006] (2) Catalyst ink is easy to cause membrane swelling and deformation during contact with SPE membrane, which affects the regularity of membrane formation
