Abstract:In polymer electrolyte fuel cells, the three-phase interface in a catalyst layer (CL) is considered to be very important as the electrochemical reaction site. The CL is typically formed using a dispersion of carbon supported platinum catalyst (Pt/C) and ionomer, and the interaction between the ionomer and Pt/C particles probably has an impact on the platinum utilization in the electrode and the dispersion stability.
In this study, we focused on the adsorptive property of ionomers onto the Pt/C… 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.
