Herein, a reduced graphene oxide–supported Prussian Blue (rGO‐PB) composite as the cathode catalyst for a passive direct methanol–hydrogen peroxide fuel cell (DMHPFC) is used. Unlike the conventional passive direct methanol fuel cell (DMFC) with a cathodic catalyst of noble metal platinum (Pt), the new fuel cell uses hydrogen peroxide as the oxidant. This nonnoble metal catalyst has a low cost, high catalytic activity, and high conductivity due to its 3D conductive network. The fuel cell has a theoretical voltage of 1.76 V (higher than 1.21 V related to the traditional DMFC) and can be used in an oxygen‐free environment. Results show that the cell shows good performance with a peak power density of 20.5 mW cm−2 at a higher temperature of 85 °C. The polarization and impedance curves indicate that as the temperature increases, the cell performance improves continuously with the decrease in mass transfer resistance. The discharging tests show a stable cell performance under continuous operation. The cell voltage has an instant response to the change in the current output.

氧化石墨烯负载的普鲁士蓝为催化剂的被动式直接甲醇-过氧化氢燃料电池

本文中,使用还原型氧化石墨烯负载的普鲁士蓝(rGO-PB)复合材料作为被动式直接甲醇-过氧化氢燃料电池(DMHPFC)的阴极催化剂。与带有贵金属铂(Pt)阴极催化剂的传统被动式直接甲醇燃料电池(DMFC)不同,新型燃料电池使用过氧化氢作为氧化剂。由于其3D导电网络,这种非贵金属催化剂具有低成本,高催化活性和高导电性。燃料电池的理论电压为1.76 V(高于传统DMFC的1.21 V),可在无氧环境中使用。结果表明,该电池表现出良好的性能,峰值功率密度为20.5 mW cm -2在85°C的较高温度下。极化和阻抗曲线表明,随着温度的升高,电池的性能随着传质阻力的降低而不断提高。放电测试表明在连续操作下电池性能稳定。电池电压对电流输出的变化具有即时响应。
