The composition of the working environments was chosen for determining the parameters of hydrogen diffusion through a 20 steel membrane by the Dewanathan–Stahursky method: the anodic cell was filled with a 0.2M KOH+10 g/ dm³ Na₂MoO₄ solution, and the cathodic cell was filled with a 1M H₂SO₄ +10 g/ dm³ (NH₂)₂ CS solution. The effective coefficient of hydrogen diffusion through a membrane made of 20 steel increases in approx. 6 times with an increase in the current density of the cathodic polarization from 0 to 2 A/ dm2 . It takes into account not only the transfer of hydrogen through the membrane but also depends on the types of traps and duration of hydrogen stay in them. The absorption of hydrogen is accompanied by an increase in the defectiveness of the metal structure, which changes the conditions of hydrogen diffusion. The dependence of hydrogen permeability through steel on time was evaluated using the Laplace equation for different probable values of the effective diffusion coefficient and hydrogen concentration. The obtained experimental results agree with theoretical calculations.

选择工作环境的组成，通过 Dewanathan-Stahursky 方法确定氢通过 20 钢膜扩散的参数：阳极池充满 0.2M KOH+10 g/ dm ³ Na ₂ MoO ₄溶液，并且阴极池填充有1M H ₂ SO ₄ +10g/dm ³ (NH ₂ ) ₂ CS溶液。通过 20 钢制成的膜的氢扩散有效系数增加约 10%。随着阴极极化电流密度从 0 A/dm2 增加到 2 A/dm2，增加了 6 倍。它不仅考虑了氢通过膜的转移，还取决于陷阱的类型和氢在其中停留的时间。氢的吸收伴随着金属结构缺陷的增加，这改变了氢扩散的条件。对于有效扩散系数和氢浓度的不同可能值，使用拉普拉斯方程评估了钢中氢渗透率对时间的依赖性。得到的实验结果与理论计算一致。
