The paper proposes the manufacturing methods for modifying coatings for gas-diffusion membranes made of palladium-silver alloy comprising 23% Ag. Highly developed surface structures are synthesized to intensify chemisorption and dissociation and to accelerate the overall process of hydrogen transmission through the membrane. At a 0.6 MPa hydrogen overpressure and 100°C temperature, the density of the hydrogen flow through Pd/Ag23 wt.% membrane with the developed surface is 7 times higher than through the similar membrane without the modifying layer. The analysis of the proposed methods shows that the hydrogen density passing through the membranes with the modifying coating synthesized by a method with the included recrystallization stage, is 1.3 times higher than through the similar membranes synthesized in accordance with the standard procedures. The experiments show that the hydrogen transmission rate can be increased in the surface limited regime by creating a highly developed structure of the membrane surface.

涂有改性层的 Pd-Ag 膜的气体传输性能

论文提出了含23%银的钯银合金气体扩散膜涂层改性的制备方法。高度发达的表面结构被合成以加强化学吸附和解离，并加速氢通过膜的整个传输过程。在 0.6 MPa 的氢气超压和 100°C 的温度下，通过具有显影表面的 Pd/Ag23 wt.% 膜的氢气密度比通过没有改性层的类似膜高 7 倍。对所提出方法的分析表明，通过包含重结晶阶段的方法合成的具有改性涂层的膜的氢密度是通过根据标准程序合成的类似膜的 1.3 倍。
