Apparatus for manufacturing electrolyte membrane and methods for manufacturing electrolyte membrane using the same

Abstract

Disclosed are an apparatus for manufacturing an electrolyte membrane and a method for manufacturing an electrolyte membrane using the same, which may prevent discoloration of the electrolyte membrane through a controlled drying process of the electrolyte membrane. The electrolyte membrane manufactured by the method of the present invention may not be discolored and performance and durability of fuel cells using the electrolyte membrane may be improved due to uniform drying of the electrolyte membrane during the manufacturing. For example, competitively simultaneous evaporation of solvents in an ionomer composition in the drying process may be prevented.
