Open publisher page 1 citations

Abstract

It is concerned that perfluorosulfonic acid(PFSA) membranes are the most critical components of proton-exchange membrane fuel cells(PEMFC) and direct methanol fuel cells(DMFC).In this article,the current status and development progress of PFSA membranes are briefly described.Some critical problems for commercial PFSA membranes,such as low proton conductivity at high temperatures and high osmosis of fuel,are discussed.Finally,combining our own researches,the development of methods for improving the PFSA membranes performances is reviewed.
