Spraying Catalysts On Nafion Membranes

Spraying Catalysts On Nafion Membranes – Auto-spraying System – Cheersonic

Ultrasonic spray coating machine for spraying Nafion membrane

Cheersonic is a world leader in precision ultrasonic coating systems, providing full coating solutions to companies and research institutes.

Cheersonic focused on the ultrasonic coating technology more than 20 years. The ultrasonic spray coating equipment from Cheersonic can deposit uniform catalyst coatings onto PEM, GDLs, electrodes, various electrolyte membranes and solid oxide fuel cells with suspensions containing, carbon black inks, PTFE binder, ceramic slurries, platinum etc.

For spraying Nafion membranes, the ultrasonic spray coating machine UAM4000 is popular in laboratory R&D and low-volume production.
(1) Programmable bench top XYZ three axis exercise and the equipment is installed with one set of ultrasonic spray system, for spraying Nafion membranes, the frequency can be 50kHz.
(2) Based on the working area ranges from 2*2 to 10*10cm, I recommend the focused type nozzle (spray width is 2-10mm).
(3) 300*300mm of combination heat and vacuum substrate plate: the max heating is up to 150℃. For spraying Nafion membranes, it needs combination heat and vacuum plate to avoid the swelling phenomenon in the spraying coating process.
(4) The liquid delivery system includes precision syringe pump and 50ml magnetic stirring dispersion syringe. The liquid delivery system is ideal for dispersing catalyst inks or slurries.
(5) 7 inch touch screen with user friendly interface R&D MCU embedded system, 3 user log in levels – Operator, Supervisor and Engineer. The storage programs is up to 999 sets.
(6) Up to 80% reduction in material consumption. Uniform and controllable coating thickness meet from ten nanometers to tens of micrometers. Coating uniformity>95%.
