Hydrogen permeability through diaphragms made of 12X18H12T stainless steel and Pd60Ag40 alloy under electrolytic hydrogen saturation has been studied with an electrolytic cell with a vacuum chamber. Hydrogen diffusion constants DH = 3.86 × 10-10 cm2 s-1 for stainless steel and DH = 4.36 × 10-8 cm2 s-1 for Pd60Ag40 alloy have been determined at a temperature of 40°C using the Berrer relations.
