Modification of Nafion Membranes with Different Clays for Direct Methanol Fuel Cell Applications

Fuel cells due to their particular properties are on the verge of creating a vast revolutionary change in the field of electricity. Proton exchange membrane fuel cells (PEMFCs) have attracted tremendous attention because of their high efficiency compared to other types of fuel cells. Nafion is the most commonly used polymer for membranes used in PEMFCs. A large variety of nanoparticles of different natures and sizes can be blended with a Nafion matrix, generating a new class of nanostructured electrolyte membrane with interesting physical properties. In this article, we summarized some of the recent works done on modification of nafion membranes with different type of clays to increase the selectivity (the ratio of proton conductivity to methanol crossover) of nanocomposite membrane in the direct methanol fuel cells
