Abstract
Permeation rates of hydrogen from H2 and H2O through steel, stainless steel and aluminium tubes of 0.1 mm thickness were determined at different temperatures, and in the case of H2 also at different pressures; the measurements with steam were carried out with superheated steam at atmospheric pressure. For H2-steel the results were in accordance with the literature; for H2-stainless steel much lower permeation rates were found than for H2-ordinary steel. For H2-aluminium the data were not reproducable and no reliable quantitative values can be given. The permeability of hydrogen from steam through steel rises very rapidly with temperature, stronger than for stainless steel, for which latter permeation rates of the same order of magnitude were found. No permeation could be detected of hydrogen from steam through aluminium within the sensivity limits of the apparatus, that is about 10-10 cm3 NTP/cm2s.
