With the development of renewable energy, proton exchange membrane fuel cells (PEMFCs) are considered as a promising candidate of next-generation energy conversion. While the design of proton exchange membranes (PEMs) have been considerably investigated over the last decades, the performance and durability are still issues in PEMFCs. We have synthesized a series of sulfonated poly(arylene perfluoroalkylene)s with well-developed morphology, high proton conductivity, good fuel cell performance and excellent oxidative stability. The relationship among the chemical structures, bulk membrane properties and fuel cell performance is discussed and reviewed. The properties of those membranes are compared with the-state-of-the-art PEM (perfluorosulfonic acid).
