计算机曲线拟合求解空气电极动力学反应参数

Reaction kinetic parameters of air electrode obtained by computer curve fitting

应用锌-空气电池装置,研究不同活性炭载体上氧气还原反应。用计算机拟合极化曲线,研究不同比表面积和孔容积的活性炭对氧气还原反应的交换电流密度、Tafel斜率、电阻等参数的影响。

Reduction performances of oxygen in the air electrodes, which were made from various active carbon powders, have been investigated by the use of zinc-air battery. Effects of active carbon powders on kinetic parameters of oxygen reduction reaction, such as exchange current density（ i0 ）, Tafel slope（ b）, reaction resistance （R）, are given by the computer curve fitting to polarization data.
