Polymer electrolyte membrane (PEM) is the heart of the direct methanol fuel cell (DMFC) system, which acts as an electrolyte for proton transfer from anode to cathode, as well as providing a barrier to the pathway of electrons between the electrodes [1]. Peruorinated (PFI) proton exchange membranes (PEMs) from DuPont, Dow Chemical, Asahi Glass, and Asahi Chemical companies, which have been used as electrolyte membranes in PEM fuel cell (PEMFC), possess outstanding chemical and mechanical stabilities. They perform excellently not only in PEMFC but also in DMFC [2,3].
