Elucidation of Ionomer-Metal Interfacial Structure by Infrared Spectroscopy, Neutron Reflectivity and Density Functional Theory
Abstract
The ionomer/electrode interface governs the electrode kinetics of polymer electrolyte batteries and fuel cells. A fundamental understanding of such interfaces is required if step improvements in electrode kinetics are to be realized. Density functional theory (DFT) was used to correlate attenuated total reflectance spectra of ionomer membranes with polarization modulated infrared reflection absorption spectra (PM-IRRAS) of ionomer-electrode interfaces.
