The results shows the capacity of the anode oxidation membrane decreases with the increasing of oxidation potential, and there exists relationship between impedance and behavior anode polarization. 提出了钽的氧化反应式及反应控制步骤;得出其氧化膜电容量随着氧化电位的增加而减少,阻抗与阳极极化行为存在相关关系。
Through anode polarization curve and electrochemical impedance chart, comparison between influences of Cl and S ions on corrosion-resistance performance of passive film on 316L stainless steel in simulated cooling water was conducted. 根据阳极极化曲线和电化学阻抗谱,比较了模拟冷却水中氯离子和硫离子对316L不锈钢钝化膜耐蚀性能的影响。
Ethanol was used as an anode fuel for polymer electrolyte fuel cells, and the electro-oxidation of ethanol on Pt-Sn/ C and Pt-Ru/ C was investigated by voltammetry and alternating current impedance method. 研究了用于直接乙醇燃料电池的自制PtSn/C阳极催化剂对乙醇的电催化氧化性能。
We have done a serial of experiments to study the PAM and anode grid with the aids of the measurement such as constant current charge/ recharge, cyclic voltammetric measurements, electric impedance spectrum and so on. 我们通过恒电流充放电、交流阻抗和循环伏安等实验方法和测试手段对铅酸电池的正极活性物质和板栅进行了一系列的研究。
With the increase in the number cycle, the anode charge transfer impedance also growing, cathode charge transfer impedance has little change. 随着循环次数的增加,负极电荷传递阻抗也不断增大,正极电荷传递阻抗变化不大。
As the resistances of three-phase interface in DSSCs with zinc oxide as anode are much larger through impedance analysis, their efficiency is lower than those of the cells with titanium oxide as anode. 通过复阻抗分析,以ZnO作阳极的DSSC三相界面电阻很大,因此其光电转化效率较低于TiO2作阳极的DSSC。
