Sono-Tek Corporation provides ultrasonic coating technology for manufacturing fuel cells, solar cells and other alternative energy products worldwide. Carbon catalysts, ceramic slurries, nanosuspensions and other functional coatings are applied using Sono-Tek ultrasonic spray nozzle systems in R&D and production volume manufacturing processes. Ultrasonic coatings are proven to have superior uniformity, durability and functionality than other coating processes. Carbon catalyst coatings applied with ultrasonic spray result in greater efficiencies than other coating methods with very little overspray of material. Ultrasonic spray nozzles are used to deposit carbon catalyst inks onto delicate Nafion membranes without ant deformation of the membrane in the manufacture of PEM fuel cells. Coatings are highly repeatable, precise and controllable via automated systems tailored to each application.
