Apparatus and method of printing catalyst on electrolyte membrane

摘要

An apparatus and a method of printing catalyst on an electrolyte membrane are disclosed. The apparatus may include: a printer head provided with an ink chamber formed in the printer head so as to store an ink, an injecting hole formed at a first side of the printer head so as to inject the ink in the ink chamber, and a piezoelectric element mounted at a second side opposite to the one side of the printer head thereby injecting the ink through the injecting hole; and a vibrator generating ultrasonic energy through vibration and applying the ultrasonic energy to the ink injected through the injecting hole so as to disperse the ink uniformly.

1. A method of printing catalyst on an electrolyte membrane, comprising:
manufacturing an ink for the catalyst; injecting the ink toward the electrolyte membrane through an injecting hole; applying ultrasonic energy to the injected ink by using a vibrator provided between the injecting hole and the electrolyte membrane; and coating the catalyst on the electrolyte membrane by dispersing the ink comprising the catalyst uniformly while applying the ultrasonic energy, the dispersed ink contacting the electrolyte membrane in a predetermined pattern.
