The diffusion of hydrogen through palladium

Abstract

Abstract The diffusion of gases through metallic septa has been the subject of much investigation, for by examining the change in the rate at which the gas diffuses with varying pressure the physical condition of the intrametallic gas has been deduced. In this field of research hydrogen-palladium has probably received the closest attention, and as the same conclusion have not always resulted from the experimental evidence, little excuse is necessary in presenting new data. Schmidt, who determined the rate of diffusion between 150° C. And 300° C., and for various pressures, concluded that while the temperature curve is probably quadratic, the pressure curve for the higher pressure may be linear, results which have been questioned by Richardson, since the experimental data when applied to this latter author’s formula for rates of diffusion gave indecisive results.
