첨가제를 이용한 촉매슬러리 조성 안정화 및 열-압착 공정 최적화 통한 PEMFC용 MEA 개발

Abstract

Process conditions for MEA fabrications have significant effects on properties and performance of the MEAs for PEMFCs. In this study, effects of additives on the surface properties of the MEA was investigated to improve homogeneity of the coated catalyst layer. Another parameter that affects on characteristics of the MEAs is hot-pressing condition. Hot pressing condition was optimized by using DOE (design of experiment)method.
