Ultrasonic nozzles produce highly durable, pinhole free coatings of carbon based catalyst inks onto fuel cell proton exchange membranes such as Nafion, without deformation of the membrane. Other metal alloys, including Platinum, nickel, Ir, and Ru-based catalyst inks and metal oxide suspensions can be sprayed using ultrasonics for manufacturing PEMs, GDLs and solide oxide fuel cells to create maximum load and high cell efficiency. Sono-Tek ultrasonic nozzles are used by some of the largest fuel cell manufacturers in the world for spraying uniform thin film layers of catalyst inks.
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.
Sono-Tek is well known for our highly durable, pinhole-free ultrasonic coatings onto Nafion fuel cells, with ultrasonic technology systems installed in some of the largest alternative energy manufacturers in the world.
In addition, Sono-Tek ultrasonic nozzles are well suited to spraying polymer solutions such as PTFE binder onto GDLs to enhance hydrophilic or hydrophobic properties in electrolyzing processes.
Customized in-house laboratory testing is available to aid in determining the best technology solution for each customer's unique process.
