ABSTRACT: The establishment of a new paradigm for energy is underway demanding new energy sources for the increasing needs of society with none or lower environmental impact. To reach the ambitious and well defined targets for decarbonized energy systems it is needed new clean technologies. Some of them rely
on well-established or emerging electrochemical devices, including batteries, fuel cells and CO2 and water
electrolysers, whose applications and performances depend on key components such as their separators/ion-exchange membranes.1,2 The most studied and already commercialized membranes go by the brand name of Nafion, which showed great chemical stability, but their high proton conduction depends on their water content, markedly limiting their operating temperature range. Our previous studies have demonstrated that the incorporation of aryl or heterocyclic phosphonic acid dopants into Nafion, by casting, results in an enhancement of the proton conductivity1-4 and stability5 of the Nafion doped membranes.
