A high performance direct peroxide-peroxide fuel cell using dendritic Pd supported on carbon fiber cloth as both the anode and the cathode is reported. Effects of the concentration of H₂O₂, KOH, H₂SO₄, the operating temperature and the flow rate on the fuel cell performance are investigated. The cell exhibits a much higher performance than those reported in the literature. The open circuit voltage reaches 0.9?V and the peak power density is as high as 14.3 and 58.4?mW?cm^?2 at 20?¡ãC and 60?¡ãC, respectively, when running on 4.0?mol?L^?1?KOH?+?1.0?mol?L^?1?H₂O₂ as the fuel and 2.0?mol?L^?1?H₂SO₄?+?2.0?mol?L^?1?H₂O₂ as the oxidant, both at a flow rate of 10?mL?min^?1.
