The purification of hydrogen gas by diffusion through a palladium sheet. Compute the number of kilograms of hydrogen that pass per hour through a 6-mm thick sheet of palladium having an area of 0.25m20.25m 2 at 600βC 600 C. Assume a diffusion coefficient of 1.7Γ10β8m2/s1.7Γ10 β8 m 2 /s that the respective concentrations at the high- and low-pressure sides of the plate are 2.0 and 0.4 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
