POLYMER ELECTROLYTE COMPOSITE MEMBRANE FOR OPERATING PEMFC AT HIGH TEMPERATURE

摘要

PURPOSE: An ion-conducting polymer electrolyte composite membrane is provided to have high ion conductivity at high temperatures more than 100 C, excellent physical durability, electrochemical stability, and thermal durability. CONSTITUTION: A manufacturing method of an Ion-conducting polymer electrolyte composite membrane comprises: a step of laminating a fiber type porous membrane, by electrospinning the solution of a polymer resin consisting of polyethersulfone; and a step of manufacturing an ion conductive polymer electrolyte composite membrane by impregnating Nafion which is an ionic conductive polymer into the porous membrane.
