Evaluation of the Properties of Protonic Conductors by Using Impedance Spectroscopy

  • Aragón Labrada, Nuñez Jaramillo


Acid solutions exhibit proton-conductivity, while pure Proton Conductors are usually dry solids. Typical materials are polymers or ceramic. Typically, the pores in practical materials are small such that protons dominate direct current and transport of cations or bulk solvent is prevented. Water ice is a common example of a pure proton conductor, albeit a relatively poor one. Proton conduction has also been observed in the new type of proton conductors for fuel cells - protic organic ionic plastic crystals (POIPCs), such as 1,2,4-triazolium perfluorobutanesulfonate and imidazolium methanesulfonate. This research work evaluates the properties of proronic conductors by using impedance spectroscopy
