Abstract: Membrane materials for proton exchange membrane fuel cells have to ensure the dual function of separating anode and cathode compartments of the fuel cell however allowing efficient transfer of protons from the anode side to the cathode side. High proton conductivity and excellent mechanical and chemical stability are required. Although perfluorosulfonic acid type membranes, of which Nafion® is the best known example, continue to show improved properties, the past 15 to 20 years have seen progress in the development of a broad range of new proton-conducting membrane types based on hydrocarbon or heterocyclic polymers and having controlled polymer and membrane architectures. This article presents the requirements for proton-exchange membrane fuel cell membrane materials for automotive and stationary application, and the associated challenges, recalls the morphology and structure of ionomer membranes and describes some current directions in the development of new proton-conducting membrane materials.
