A direct hydrazine fuel cell using H2O2 as the oxidizer has been developed. The N2H4/H2O2 fuel cell is assembled by using Ni-Pt/C composite catalyst as the anode catalyst, Au/C as the cathode catalyst, and Nation membrane as the electrolyte. Both anolyte and catholyte show significant influences on cell voltage and cell performance. The open-circuit voltage of the N2H4/H2O2 fuel cell reaches up to 1.75 V when using alkaline N2H4 solution as the anolyte and acidic H2O2 solution as the catholyte.A maximum power density of 1.02 W cm(-2) has been achieved at operation temperature of 80 degrees C. The number of electrons exchanged in the H2O2 reduction reaction on Au/C catalyst is 2. (C) 2010 Elsevier B.V. All rights reserved.
