Abstract:Polymer electrolyte fuel cells (PEFCs) are attractive energy resources in transportation and portable applications due to their low operational temperatures, excellent energy densities, and simplicity of storage. For the past decade, metal oxides (MO) have been identified as plentiful supplies with excellent electrochemical properties, low cost, an abundance of hydroxyl groups, and environmentally acceptable alternative to currently available materials. Their intriguing properties such as extremely large surfa… 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.
