Programmable Desktop High-precision MEA Spraying Machine
The Programmable Desktop High-precision MEA Spraying Machine is an experimental grade equipment dedicated to precision coating of catalyst slurry, which can achieve precise positioning and uniform spraying of catalyst coatings. It is widely used for sample production of various configurations such as CCM (catalyst coating film) and GDE (gas diffusion electrode) in the preparation process of catalytic layers. The system integrates an automated motion control module, which drives a high-precision X-Y axial movement platform through preset programs to achieve spraying operations of complex patterns and specified paths, thereby completing highly consistent membrane electrode preparation on small and medium-sized substrates. The device has a compact overall structure, small footprint, and light weight, making it easy to flexibly arrange and use in conventional experimental environments. The operation process has been simplified and designed, and even non professionals can quickly master it. It is suitable for sample development and small-scale trial production needs in various research institutes, university laboratories, and enterprise R&D departments in fields such as fuel cells and electrochemical catalysis.
Compared with traditional ultrasonic atomization spraying equipment, this system significantly reduces the size and overall weight of the equipment while maintaining spraying accuracy, making it more suitable for deployment on laboratory tables with limited space, and improving the versatility and ease of operation of the equipment. Compared to handheld pneumatic spraying devices that rely on manual operation, this equipment has a high level of automation and intelligence. The system can independently control the gas and liquid paths of the spray nozzle, including key parameters such as opening and closing status, gas flow rate, and slurry supply rate. It can also automatically control the start and stop of spraying, the duration of nozzle stay at specific positions, and the movement speed according to program settings, thereby accurately controlling the slurry deposition amount and coating distribution in each area.
This precise control mechanism not only achieves accurate reproduction of spray trajectory and coverage area, but also significantly improves the uniformity and structural consistency of the catalyst coating. The prepared membrane electrode exhibits good repeatability in thickness control, microstructure, and electrochemical performance, which is conducive to systematic process research and performance verification. In addition, the device can be used not only for spray coating preparation of membrane electrodes, the core component of fuel cells, but also for carrier coating, functional layer construction, and uniform dispersion and loading of various catalyst slurries in the process of assisting catalyst synthesis. It has broad potential for application in new energy material research and development, electrochemical device manufacturing, and other fields.
In summary, this type of spraying system, with its precise control capability, flexible programming characteristics, and excellent coating quality, provides a reliable and efficient process platform for the research and development of laboratory level membrane electrodes and related materials, which helps to promote the rapid verification and technological iteration of new materials and structures in related fields.
