Abstract: The invention relates to pure hydrogen membrane extraction from hydrogen-containing gas mixtures. The aim of said invention is to increase the performance and service life of membranes. The inventive flat sealed filtering element comprises two walls, a separating porous element arranged therebetween and a hydrogen-removing pipe. The walls consist of water permeable membranes made of a palladium alloy and sealingly connected to each other in frames. The wall membrane is shaped in the form of the relief consisting of protrusions and recesses, which are uniformly distributed along the working surface thereof. The ratio between the protrusion length (L) in a normal cross-section and the projection (D) thereof ranges from 1.05 to 1+d, wherein d is the membrane material plasticity. The relief makes it possible to increase the strength, reliability, service life and the performance of the membrane due to the modification of the surface area and thickness thereof. The membrane device comprises a body, a set of parallel filtering elements, gas supplying and gas removing elements, which enable an initial mixture to flow from the periphery to the center, a weak mixture to be discharged from the membrane center, prevent the formation of dead zones and make it possible to attain the maximum degree of hydrogen extraction.
