Ultrasonic Coating System for PEMWE MEA Catalyst Coating
Our lab-scale ultrasonic spray coating system is purpose-built for precision catalyst deposition in PEMWE (Proton Exchange Membrane Water Electrolysis) MEA fabrication. Optimized specifically for academic R&D, laboratory prototyping, and small-batch material testing, this equipment delivers highly uniform, thin, and pinhole-free catalyst layers while preserving the integrity of fragile proton exchange membranes. It addresses the critical limitations of traditional coating methods, including uneven coverage, low catalyst utilization, and substrate damage, becoming an ideal solution for PEM water electrolyzer research.
Engineered to match mainstream lab research parameters, the system perfectly adapts to standard 25 cm² PEMWE MEA samples and common catalyst ink viscosity at 10 mPa·s, fully compatible with Ir-based, Pt-based, and other precious metal catalyst slurries for hydrogen production electrolyzer MEAs.

Core Advantages for PEMWE Laboratory Research
1. Ultra-High Coating Uniformity & Experimental Repeatability
Different from air-brush and manual coating with uncontrollable atomization, our ultrasonic technology vibrates catalyst ink into micron-level fine and uniform droplets. The programmable CNC control system precisely adjusts spray speed, working height, and coating layers, ensuring consistent catalyst layer thickness and even ionomer distribution on 25 cm² MEA samples. Stable and repeatable coating results guarantee credible experimental data, which is vital for PEMWE performance research and academic publication.
2. High Precious Metal Catalyst Utilization
PEMWE catalyst materials (iridium, platinum, etc.) are costly. The low-pressure soft deposition mode of ultrasonic spray coating effectively reduces ink splashing and over-spray waste, greatly improving catalyst utilization rate compared with traditional spraying processes. It significantly cuts down the experimental cost of long-term laboratory research and multi-batch process iteration.
3. Zero Damage to Fragile PEM Substrates
Traditional high-pressure spraying easily causes membrane deformation, wrinkling or even rupture, affecting MEA electrolysis performance. This system adopts non-contact low-speed droplet deposition, which will not damage the delicate proton exchange membrane structure. It maintains the original physical and chemical properties of the membrane, ensuring accurate evaluation of catalyst and MEA assembly performance.
4. Flexible & Lab-Friendly Operation
Designed for laboratory scenarios, the compact equipment structure saves bench space with simple parameter debugging. Researchers can freely adjust coating thickness, catalyst loading and spray paths according to different experimental schemes, supporting diverse innovative research on PEMWE MEA formula optimization and process upgrading.
