Abstract

In this work, we propose to create the cathode potential by introducing a redox couple to the cathode while to use hydrogen peroxide to chemically charge to redox ions. Experimentally, it is demonstrated that the ethanol-hydrogen peroxide fuel cell with a redox couple of V4/V5 yields a peak power density of 450 mW cm^-2, which is much higher than that of the conventional cell with direct reduction of hydrogen peroxide.
