将用于测量氢渗透到钢板中的Devanathan-Stachurski电化学电池扩展到电解质流动设计。入口电池的流速的增加引起入口电极处的析氢电流的增加，但引起氢出口电极处的氢渗透电流的减少。氢气渗透是通过入口流量的正弦扰动来实现的。氢渗透响应，即，从进化电流的检测电流的相移，是成比例的流速频率的平方根，并依赖于片材厚度。入口流量的正弦扰动是影响氢渗透的一个新因素。
The Devanathan-Stachurski electrochemical cell for measurement of hydrogen-permeation into a steel sheet was extended to an electrolyte-flowing design. Increase in flow rate of the entry cell induces increase in hydrogen-evolution current at the entry electrode but decrease in hydrogen-permeation current at the hydrogen-exit electrode. Hydrogen-permeation is actualized by a sinusoidal perturbation of the entry-flow rate. The hydrogen-permeation response, ie, phase shift of the detection current from the evolution current, was proportional to the square root of flow rate frequency and was dependent on sheet thickness. The sinusoidal perturbation of entry-flow rate is a new factor influencing hydrogen-permeation into the sheet.
