METHOD FOR PRE-PROCESSING OF HYDROCARBON-BASED ELECTROLYTE MEMBRANE HYDROCARBON-BASED ELECTROLYTE MEMBRANE MANUFACTURED BY THEREOF AND MEMBRANE ELECTRODE ASSEMBLY COMPRISING HYDROCARBON-BASED ELECTOLYTE MEMBRANE

摘要

The present invention provides a method for pre-processing a hydrocarbon-based electrolyte membrane, a hydrocarbon-based electrolyte membrane manufactured thereby, and a membrane electrode assembly including a hydrocarbon-based electrolyte membrane. The method for pre-processing a hydrocarbon-based electrolyte membrane for a fuel cell comprises the following steps of: exfoliating a hydrocarbon-based electrolyte membrane from a substrate and a laminate including the hydrocarbon-based electrolyte membrane provided on the substrate; and storing the hydrocarbon-based electrolyte membrane in which the substrate is exfoliated at a temperature of 60 to 150°C and a humidity of 60 to 95% for 0.5 to 20 hours, or immersing and storing in water at 40 to 90°C for 0.5 to 24 hours.
