Sono-Tek offers ultrasonic thin film coating for fuel cells or solar cells.
Coatema: Coating machinery
Customized design and manufacturing
Together with Coatema we construct and manufacture individual machinery for coating, printing and laminating for laboratory, pilot and production applications. Every machine is a specially construction to sever the needs of our clients.
Equipment for lab, pilot and production plants
Coatema offers both single aggregates and turn-key production plants for discontinuous and continuous processes for all sizes from DIN A4 to working widths of 5,400 mm.
Laboratory equipment: Laboratory machines are used for the development of products and procedures.
Pilot equipment:Pilot plants are used for the production of small quantities of finished materials to establish most of the parameters that would be used in full production.
Production plants: Production plants are used when the output demands are high.

Ultrasonic thin film coating
Ultrasonic thin film coating systems for solar cells
Ultrasonic advantages with SelectaFlux for solar cells:
• Proven technology in high-volume solar cell manufacturing (100s of machines installed)
• Ability to control flux thickness
• Ultrasonic nozzles never clog
• No overspray
• Good edge definition
• Only monthly maintenance
• Simple adjustment of spray width from 2 mm – 5 mm by adjusting distance to solar cell
• Non-contact fluxing method
• Spray up and spray down configurations
Ultrasonic coating systems for fuel cells
Ultrasonic nozzles are ideal for spraying the catalyst layer onto a wide range of fuel cell substrates, including:
• PEMs
• GDLs
• Electrodes
• Various electrolyte membranes
• Solid oxide fuel cells (SOFCs)
• Rods and buttons with ceramic slurries
• Catalyst suspensions containing carbon black ink or other conductive inks such as platinum, nickel, Ir or Ru.
The uniform thin film coating achieved with ultrasonics retains the porosity of the electrode and does not impede the transport of reactants due to flooding of the electrode surface. Catalyst solutions will not clog the ultrasonic nozzle, allowing for precise coatings with controlled droplet sizes at ultra-low flow rates.
