Abstract:This study examines the atomic confinement of commercial Pt/C electrocatalysts. While a high electrocatalytic activity for the oxygen reduction reaction is important for proton-exchange membrane fuel cell (PEMFC) performance, the high stability of the electrocatalyst is essential for real applications under harsh operating conditions. The demands necessitate the development of advanced electrocatalysts that are resistant to corrosion. A combination of diazonium chemistry with Cu electrodeposition permits the s… Show more
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.
