| Abstract: | 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 D
H = 3.86 × 10−10 cm2 s−1 for stainless steel and D
H = 4.36 × 10−8 cm2 s−1 for Pd60Ag40 alloy have been determined at a temperature of 40°C using the Berrer relations. |
