The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. calculate the number of kilograms of hydrogen that pass per hour page 2 of 3 through a 6 mm thick sheet of palladium having an area of 0.25 m2 at 600°c. assume a diffusion coefficient of 1.7 × 10-8 m2 /s, that the concentrations at the high and low pressure sides of the plates are 2.0 and 0.4 kg/m3 of hydrogen per cubic meter of palladium, and that steady state conditions have been attained.
