Using the electrode based on various core- shell electrocatalyst in polymer electrolyte fuel cells

Recently the core@shell structures are attractive. Researchers were attention to these structures for electrocatalytic applications. Many methods have been reported for synthesis of core@shell. In this work, we attempt to discuss the several studies including: different metal that using as a core or shell, synthesis techniques, and finally electrochemical performance and physical characterization of synthesised electrocatalyst. In addition to, a number of examples are presented to illustration the various applications of such structures and impart the enhancement of electrocatalytic performance due to core@shell structures
