A low-cost, high-performance zinc-hydrogen peroxide fuel cell

In this work, we report a catalyst-free, high-performance zinc-hydrogen peroxide fuel cell that consists of a redox flow cell with the respective redox couple at the anode (V(II)/V(III)) and cathode (V(IV)/V(V)) regenerated by the fuel (zinc) and the oxidant (hydrogen peroxide), which exhibits an extraordinarily high peak power density of 1192 mW cm−2 at 60 °C, a performance which is about six times higher than that of state-of-the-art conventional fuel cells of the kind (∼200 mW cm−2).122
