Methods to modify the surface of Pd-23% Ag alloy films were developed in order to increase the velocity of hydrogen transmission; we obtained palladium coating of “nanostars” and “nanopores” type. Modification of Pd-Ag films surface, obtained by nanostars palladium coating makes it possible to achieve a hydrogen flow density of 0.76 mmol / (s*m2), which is 1.6 times greater in comparison with modification by “nanopores” coating under low temperature (<90 ° C) and pressure (<0.6 MPa) conditions.
