Abstract:Proton-conducting ceramics based on perovskite-type oxides have been significantly applied in a wide range of electrochemical devices such as fuel cells, hydrogen sensors, and steam electrolysers. One of the emerging applications of these ceramic proton conductors is as an electrolyte component in a solid oxide fuel cell (SOFC), where the proton is mobilized from the anode to the cathode side via these conductors. The proton (hydrogen ion) diffusion mechanisms and activation energies (Ea) in these materials ar… 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.
