多壁碳纳米管为阴极材料的单室过氧化氢燃料电池

Multi-walled Carbon Nanotubes as Cathode Material for One-compartment Hydrogen Peroxide Fuel Cell

以多壁碳纳米管负载在碳纸上作为阴极材料,镍网作为阳极材料,在酸性电解质中,构成了一个单室过氧化氢燃料电池。该过氧化氢燃料电池的最大功率密度为4080mW/m2,高于仅以碳纸作为阴极材料(28mW/m2)的电池。结果表明,该单室过氧化氢燃料电池有潜力发展成为便携式和小型化的应用电源。

Multi-walled carbon nanotubes coated on carbon paper was exploited as a cathode material for constructing a one-compartment hydrogen peroxide fuel cell,while anode was made of nickel mesh.The maximum power density of this H2O2 fuel cell is 4080 mW/m2,which is far higher than that of the fuel cell with carbon paper as cathode materials only（28 mW/m2）.The results indicated that this single-compartment H2O2 fuel cell is a promising power source for portable and miniaturized applications.
