The proton exchange membrane is a key component of Direct Methanol Fuel Cell (DMFC)
as proton conductor and also fuel separator. Some novel polymeric electrolyte membranes
for DMFC with have been developed to lower methanol permeability but are able to work at
sufficient conductivity. The composite of the natural polymer chitosan and sulfonated
polyether ether ketone was prepared. This composite membrane was characterized using
Fouriertransform infrared spectrometry, X-ray diffraction, water uptake and swelling degree …
