The ultrasonic conical spray nozzle for flat‑material PEM fuel cells is fitted with an air shroud. It generates broad vortex‑driven atomization, making it well‑suited for coating flat substrates including PEM fuel cells and solar cells. A reciprocating vortex‑style nozzle is recommended for this application, paired with a basic XY positioning stage.

This ultrasonic conical spray nozzle delivers a medium‑coverage spray footprint. Its spray width exceeds that of focused ultrasonic nozzles, yet is narrower than the coverage produced by wide‑format ultrasonic nozzles. The vortex‑type ultrasonic nozzle relies on low‑velocity swirling gas flow to achieve a uniform, broad spray pattern. It forms a conical spray coverage ranging from 2‑4 inches (50‑100 mm) in diameter; the exact dimension varies with stand‑off distance to the substrate. Vortex airflow speed can be adjusted to match specific process requirements.
