고온형 고분자전해질연료전지용 MEA 개발 및 응용

Abstract

Proton exchange membrane Fuel Cells(PEMFCs) have been spotlighted because of their broad potential application for potable electrical devices, automobiles and residential usages. However, their utilization is limited to low temperature operation due to the electrolyte dehydration at high temperature. High temperature PEMFC operation offers high CO tolerance and easy water management. This review presents development of high temperature(120~200℃) PEMFC. Especially, PEMFC which is based on acid-doped PBI membrane is discussed.
