摘要: 研究了碱性燃料电池合成过氧化氢阴极碳/聚四氟乙烯(C/PTFE)的制备方法, 考察了制备过程中的主要影响因素,并通过伏安曲线和过氧化氢浓度曲线及交流阻抗图谱,对不同条件下制备的阴极性能进行了评价. 结果表明,压力、整平层碳含量及聚四氟乙烯含量对阴极性能均有较大影响,其中压力为10.0 MPa、碳含量为0.2 g及聚四氟乙烯含量为50%条件下制备的阴极能获得最大电流,过氧化氢的产量最高,2.5 h后过氧化氢浓度达到56 mmol/L.

Abstract: A fabricating method of C-polytetraflouroethylene cathode, C/PTFE, for hydrogen peroxide synthesis through alkaline fuel cell reactor was studied, and the primary influential factors of fabrication were investigated. The performances of cathodes at different fabricating conditions were evaluated by the voltage-current curve, concentration curve of H2O2 and AC impendence diagram. The results showed that cathode performances were much affected by the pressure, carbon content and PTFE content in the flattening layer. When the pressure was 10.0 MPa, carbon content 0.2 g, and PTFE content 50%, the maximum current and high output of H2O2 were produced, and the concentration of H2O2 reached 56 mmol/L after 2.5 h.

Key words: hydrogen peroxide, alkaline fuel cell, C/PTFE cathode, fabrication, characterization
