Among several types of fuel cells, polymer electrolyte membrane fuel cells (PEMFC) have been regarded as promising options for electrical vehicles. The vital component of PEMFC is a proton conducting membrane. The state-of-the-art technology is mostly based on perfluorinated membrane materials, such as Nafion(R) (DuPont, USA), Flemion(R) (Asahi Glass, Japan) and Aciplex(R) (Asahi Kasei, Japan). Because of involvement of expensive fluorine chemistry, the membrane material costs represent (in addition to the catalyst) the major contribution to the membrane electrode assembly (MEA) price. Much effort has been focused during the last decades on the development of new, lower cost membrane materials possessing suitable properties.
