Abstract
The presented project aims at the development of an in-situ characterization method for the development of new proton conducting Metal-Organic Frameworks (MOFs). A novel combination of water sorption technique with impedance spectroscopy allows identification of proton conduction mechanisms in complex nanomaterials. On standard proton conducting materials (e.g. Nafion) the relative humidity determines the dominating conduction type (proton hopping, Grotthuss or vehicle mechanism). Discrimination is possible by temperature resolved studies, which can be utilized for optimization of specifically designed, humidity-independent proton-conducting MOFs. First results on the characterization of the novel setup as well as on single crystal MOF materials will be presented.
