Abstract Radiation-induced graft copolymerization is an attractive technique to prepare alternative proton conducting membranes (PCMs) for fuel cell applications. The purpose of this chapter is to review the latest progress made in the development of various radiation-grafted PCMs for fuel cells. The challenges facing the development of these membranes and their expected future research directions are also discussed. 

Strongly acidic (sulfonic acid) membranes have been identified for use as solid polymer electrolytes in fuel cells [28]. Preparation of these membranes by radiation induced graft copolymerization has been reported and reviewed in various occasions [23,24,27]. Historically, the first radiation grafted sulfonic acid membranes were prepared by Chen et al. [29] through grafting of styrene onto polyethylene (PE) films and used for battery separators and dialysis. However, most of the early woik on radiation-grafted membranes was carried out and reviewed by Chapiro [30].
