Carbon-supported Co@Au core-shell/C and Au/C nanoparticles are synthesized by a suc- cessive reduction method in an aqueous solution and used as the anode and cathode electrocatalysts for the direct hydrazine-hydrogen peroxide fuel cell, respectively. The physical and electrochemical properties of the as-prepared electrocatalysts are investi- gated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X- ray spectroscopy (EDS), and fuel cell field tests. In this work, the effects of different oper- ation conditions including operation temperature, fuel and oxidant concentration and fuel and oxidant flow rate on the performance of fuel cell are systematically investigated. The experimental results exhibit an open circuit voltage of about 1.79 V and a peak power density of 122.75 mWcm2 at a current density of 128mA cm2 and a cell voltage of 0.959 V operating on 2.0 M N H and 2.0 M H O at 60 C.
