Radiation Grafted Membranes for Fuel Cells: Strategies to Compete with PFSA Membranes

Abstract

Radiation grafted proton conducting membranes are developed with the prospect of low cost, while aiming at maintaining or improving the functionalities of PFSA ionomer membranes. We show key polymer design aspects (base film, grafting monomer, processing) to prepare membranes that show favorable performance and durability attributes in the fuel cell compared to commercial Nafion 212 and Nafion XL-100 membranes.
