已经开发出使用H 2 O 2作为氧化剂的直接肼燃料电池。通过使用Ni–Pt / C复合催化剂作为阳极催化剂，Au / C作为阴极催化剂以及Nafion膜作为电解质组装N 2 H 4 / H 2 O 2燃料电池。阳极电解液和阴极电解液都显示出对电池电压和电池性能的重大影响。当使用碱性N 2 H 4溶液作为阳极电解液和酸性H 2 O 2时，N 2 H 4 / H 2 O 2燃料电池的开路电压达到1.75 V溶液作为阴极液。在80°C的工作温度下已达到1.02 W cm -2的最大功率密度。在Au / C催化剂上的H 2 O 2还原反应中交换的电子数为2。

A development of direct hydrazine/hydrogen peroxide fuel cell
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 Nafion 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 °C. The number of electrons exchanged in the H2O2 reduction reaction on Au/C catalyst is 2.
