Membraneless hydrogen peroxide micro semi-fuel cell for portable applications

Abstract

This communication describes the first one-compartment hydrogen peroxide semi-fuel cell as a micro-power source for miniaturized applications. This power source is inspired by the high energy content of metals and producing a light-weight, adaptable design that is easy to package. Theoretical specific energy densities of 8600 and 17 000 W h kg−1 are achievable for the power source by oxidation of magnesium (Mg) or aluminium (Al) at the anode side in combination with the reduction of hydrogen peroxide at the cathode side. We have fabricated a cell with Mg as the anode and Prussian blue as the cathode that had an open-circuit potential of 2.3 V and a net maximum power density of 7.5 mW cm−2. These results are the highest ever reported for a one-compartment H2O2-based power source. This cell design can provide a platform for fabricating a new generation of power sources for portable and miniaturized applications.
