Studies of electrochemical performance of carbon supported Pt–Cu nanoparticles as anode catalysts for direct borohydride–hydrogen peroxide fuel cell

摘要: Abstract Carbon supported Pt–Cu bimetallic nanoparticles are prepared by a modified NaBH4 reduction method in aqueous solution and used as the anode electrocatalyst of direct borohydride–hydrogen peroxide fuel cell (DBHFC). The physical electrochemical properties as-prepared electrocatalysts investigated transmission electron microscopy (TEM), X-ray diffraction (XRD), cyclic voltammetry (CV), chronoamperometry (CA), chronopotentiometry (CP) test. results show that carbon catalysts have much higher catalytic activity for oxidation BH4− than pure nanosized Pt catalyst, especially Pt50Cu50/C catalyst presents highest among all catalysts, DBHFC using Pt/C cathode shows high 71.6 mW cm−2 power density at discharge current 54.7 mA cm−2 25 °C.
