The present invention provides a method for manufacturing a fuel cell membrane-electrode assembly by ultrasonic vibration bonding, which prevents damage to the membrane-electrode assembly by an ultrasonic vibration horn. That is, the present invention provides a method for manufacturing a fuel cell membrane-electrode assembly in such a manner that a sub-gasket is bonded to both sides of a polymer electrolyte membrane using ultrasonic vibration and, subsequently, an electrode is coated and dried on both sides of the polymer electrolyte membrane which exposed through an opening of the sub-gasket, thereby preventing the membrane-electrode assembly from being damaged. |
