Nafion/Poly Vinylidene Fluoride (PVDF) Blends for Polymer Electrolyte Membranes Application

Abstract

The proton exchange membrane fuel cells have attracted tremendous attention recent years because of their highest efficiency compared to other types of fuel cells. Nafion , a perfluorinated polymer substituted by sulfonic acid groups, is the most commonly used polymer for the fabrication in proton exchange fuel cell membrane. A large variety of nanoparticles of different nature and size can be blended with Nafion matrix, therefore, generating a new class of nanostructured electrolyte membrane with interesting physical properties. These membranes have attracted both academic and industrial attention because they exhibit significant improvement in thermomechanical and thermal stability as well as proton conductivity at a very low filler contents.
