Аннотация: Abstract—The purity of hydrogen, which is an alternative energy carrier in powder sources of distributed energyresource systems and, in particular, is the feed stock for fuel cells, should be no less than 99.9999 vol % purityHigh-purity hydrogen can be prepared only via its separation as a result of selective diffusion through metallicmembranes manufactured from specific membrane palladium-based alloys prepared in the form of thin foils.In the present work, the combination of deformation and annealings under different conditions is used to preparethe Pd–7.70 wt % Lu alloy in the form of foil 50 μm thick, whose specific hydrogen permeability is studiedin the course of cyclic heating and cooling in a hydrogen atmosphere in a temperature range of 300–500°С. The Pd–7.70 wt % Lu membrane is shown to demonstrate high and stable hydrogen permeability. Theevolution of the surface structure of the membrane in the course of its operation in the hydrogen atmosphereis studied by atomic force microscopy using the phase contrast mode
