Synthesis and properties of novel sulfonated polyimide membranes for direct methanol fuel cell application

Proton exchange membrane fue cells (PEMFCs)have been receiving considerable attention as electrical power sources in the 21st century because of their high energy efficiency and low pollution levels for the environment. Direct methanol fuel cells (DMFCs) as a new born kind are becoming more and more attractive as mobile and portable power sources for cell phones, notebook computers and other electronic devices.Sulfonated polyimides (SPIs) are one of the promising candidates for fuel cell applications because of their high thermal stability, good mechanical strength and modulus, superior chemical resistance, and excellent film forming ability.What is more,when used in DMFCs,sulfonated polyimides displayed significantly lower methanol permeability than perfluorosulfonated polymers such as Nation,and this made them attracting more and more attention in this field.
