研究了利用脉冲放电从水中高效制氢的方法。本文采用气相色谱仪热导检测器，研究了施加脉冲电压参数和水条件对制氢过程的影响。放电介质分别为氩气和蒸馏水。将磁脉冲压缩电路形成的纳秒级脉冲电压施加到垂直放置在水面上的针电极上。在气体和水之间观察到树状流带放电。产氢率与施加电压和脉冲重复率成正比。不同初始水温和电导率对产氢速率无显著影响。在本研究中，制氢的峰值能源效率约为。1500 kJ / L。
The efficient hydrogen production from water by using pulsed electrical discharge has been developed. In this paper, the influence of applied pulsed voltage parameters and water conditions on hydrogen production process was investigated by using gas chromatograph with thermal conductivity detector. Argon gas and distilled water were used as discharge medium, respectively. The nanosecond pulsed voltages that was formed by magnetic pulse compression circuit were applied to a needle electrode vertically-placed over water. The tree-like streamer discharge was observed between gas and water. Hydrogen production rates were proportional to applied voltage and pulse repetition rate. No significant differences in the hydrogen production rate were confirmed among the different initial water temperatures and conductivities. In this study, the peak energy efficiency of hydrogen production is approx. 1500 kJ/L.
