Abstract:
The present invention relates to a method of manufacturing an electrolyte membrane for fuel cells by transferring antioxidants to the electrolyte membrane. The method may include providing a first membrane including a perfluorinated sulfonic acid-based compound, providing a second membrane including an antioxidant such that the second membrane partially or entirely contacts a surface of the first membrane, transferring or moving the antioxidant of the second membrane to the first membrane, and removing the second membrane.
