Polysulfone-Based lonomers

CNRS-Grenoble INP - UJF, Saint Martin d Heres, France [Pg.81]

This chapter is a review focussed on the development of ionomers based on aromatic polysulfones for their application as Polymer Electrolyte Membrane (PEM) in Proton Exchange Membrane Fuel Cells (PEMFC) or in Direct Methanol Fuel Cells (DMFC). Different types of synthesis routes have been discussed in this chapter in order to obtain ionomers based on polysulfones with variation in structural designs. Special attention is given to the impact of the structural design of the ionomer on various properties such as membrane morphology, thermo-mechanical stability and protonic conductivity of the membranes for their utilization as PEMs. [Pg.81]

The cheapest alternative is sulfonated polyst5n-ene [7,8] but, due to the high sensitivity of its benzylic sites to free-radicals and oxidants, it cannot be used as a PEM. [Pg.82]
