The progress of hybrid proton exchange membranes prepared by SPAEKs for direct methanol fuel cells

摘要

This review summarizes efforts in developing proton exchange membranes (PEMs) with excellent electrochemical fuel cell performance prepared by SPAEK in proton exchange membrane fuel cell (PEMFC) applications. Over the past few decades, much polyelectrolyte has been extensively studied to improve the properties as alternatives with lower cost and considerable performances for PEMFC. Sulfonated poly(aryl ether ketone) (SPAEK), fell into this category, which offers the attribute of adjustable proton conductivity, excellent mechanical and thermal stability. The discussion will cover crosslinking, organic-inorganic nanocomposite, layer-by-layer approaches.
