Fuel Cell Catalyst Coating System
Fully enclosed XYZ tabletop ultrasonic spraying system designed for depositing catalyst coatings onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals.
Sono-Tek ultrasonic nozzles feature:
- Up to 80% reduction in material consumption
- Reduced wasteful overspray and atmospheric contamination
- Non-clogging design results in minimal servicing and downtime
- Repeatable spray patterns that are easily shaped for precise coating applications
- Highly controllable spray produces reliable, consistent results with or without masking
- Corrosion-resistant titanium and stainless steel construction
- No moving parts to wear out
Uniform nanocoatings of catalyst ink are deposited onto Nafion fuel cells without deformation of the membrane. The high degree of uniformity achieved with ultrasonic spray ensures the maximum surface area exposure of platinum in Hydrogen fuel cell coating construction.
The ExactaCoat FC features:
- Precise substrate uniformity with repeatability down to ±2%
- Compact benchtop design that favors portability
- 400 mm x 400 mm x 100 mm (15.75″ x 15.75″ x 3.94″) range of motion
- Windows®-based programming software with image import
- Remote trackball teach pendant
- Coordinated motion in all three axes simultaneously
Optional Equipment
- Heat plate
- Vacuum plate
- Combined heat/vacuum plate
- Ultrasonic dispersion pump
- MicroFlow recirculation pump
- Camera (Passive Vision)
Nozzles can be integrated with the following air shaping technologies:
