Advances in Membrane Electrode Assembly for Direct-Methanol Fuel Cells Zhang Jun, Xu Li, Wang Yuxin (School of Chemical Engineering Chemical Engineering Research Center, Tianjin University, Tianjin 300072) Abstract Researches on polymer membrane direct-methanol fuel cells (DMFC) have made great advances since mid 1990s. Due to its increasing commercial prospect, DMFC is being concerned more and more. Optimizations of the structure and preparation processes of membrane electrode assembly (MEA) for DMFC are reviewed，and the problems of MEA for DMFC are analyzed in this article.
