▎ 摘　　要

Herein, a reduced graphene oxide-supported Prussian Blue (rGO-PB) composite as the cathode catalyst for a passive direct methanol-hydrogen peroxide fuel cell (DMHPFC) is used. Unlike the conventional passive direct methanol fuel cell (DMFC) with a cathodic catalyst of noble metal platinum (Pt), the new fuel cell uses hydrogen peroxide as the oxidant. This nonnoble metal catalyst has a low cost, high catalytic activity, and high conductivity due to its 3D conductive network. The fuel cell has a theoretical voltage of 1.76 V (higher than 1.21 V related to the traditional DMFC) and can be used in an oxygen-free environment. Results show that the cell shows good performance with a peak power density of 20.5 mW cm(-2) at a higher temperature of 85 degrees C. The polarization and impedance curves indicate that as the temperature increases, the cell performance improves continuously with the decrease in mass transfer resistance. The discharging tests show a stable cell performance under continuous operation. The cell voltage has an instant response to the change in the current output.
