We reports on a unique characterization method for the electrode reactions of SOFCs via impedance spectroscopy combined with a spatially-constricted contact based on a robust electrolyte which is expected to give more reliable measurement set-up. Various electrode materials were chosen to validate our method and the corresponding impedance phenomena were analyzed to give an insight for optimization of the SOFC electrode. The ramifications of "limited-contact" impedance spectroscopy are discussed for an exhaustive understanding of electrode-related polarizations in SOFCs
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
