โœฆ Synopsis

A direct hydrazine fuel cell using H 2 O 2 as the oxidizer has been developed. The N 2 H 4 /H 2 O 2 fuel cell is assembled by using Ni-Pt/C composite catalyst as the anode catalyst, Au/C as the cathode catalyst, and Nafion membrane as the electrolyte. Both anolyte and catholyte show significant influences on cell voltage and cell performance. The open-circuit voltage of the N 2 H 4 /H 2 O 2 fuel cell reaches up to 1.75 V when using alkaline N 2 H 4 solution as the anolyte and acidic H 2 O 2 solution as the catholyte. A maximum power density of 1.02 W cm -2 has been achieved at operation temperature of 80 โ€ข C. The number of electrons exchanged in the H 2 O 2 reduction reaction on Au/C catalyst is 2.
