Hydrogen peroxide (H2O2) and the reduction/oxidation by-products of peroxide are non-toxic to humans and the environment. Simple, low-concentration hydrogen-peroxide solutions used as fuel and direct peroxide/peroxide fuel cells (DPPFCs) face significant challenges in the development of a new class of power generators. A power density of 10 mWcm−2 at a cell potential of 0.55 V have been achieved with a DPPFC composed of carbon-paper-supported nickel as the anode catalyst and carbon-paper PbSO4 as the cathode catalyst. The catalysts have been prepared by electroless deposition. Using non-precious metals rather than platinum in our FC makes the cell cost effective comparable to that of PEMFCs. Additionally, as a low-price fuel, H2O2 reduces the cost of this FC.
