通过用具有50微米，特别是2至20微米，选择性氢气可渗透金属箔（3）<100微米，特别是10至30 FIM中，一个最大网眼宽度的至少一个相应的精细网孔的金属网或织物（1,2）双边支撑薄 氢气渗透壁获得足够的稳定性，这是保护免受污垢和制造技术有利。 优选地，这种三层布置的表面通过打褶或起皱而增加。 在与薄膜邻接的细网眼织物后面，更加粗糙的支撑结构可能是适宜的。 细金属网上的扩散抑制或抗腐蚀涂层可显着延长组件的使用寿命（图1）。

Thin through bilateral support with at least each a fine mesh metal mesh or fabric (1,2) with a maximum mesh width of 50 .mu.m, more preferably 2 to 20 .mu.m, selective hydrogen permeable metal foil (3) of <100 microns, especially 10 to 30 _fi m with sufficient stability obtained a hydrogen Permeationswand which is protected against dirt deposits and low production engineering. Preferably, the surface of such a tri-layer structure is increased by pleating or corrugation. Behind the fine mesh cloth adjacent to the foil may be appropriate to further coarser support structure. Diffusion-resistant or corrosion protective coatings on the fine metal mesh to the life of the assembly significantly increase (Fig. 1).
