Abstract

The diffusion of deuterium through a Pd<sub>81</sub>Pt<sub>19</sub> membrane was investigated. At six temperatures in the range 278.2-328.2 K the diffusion coefficients were determined by breakthrough method for the membrane with no initial content of deuterium. The determined activation energy of diffusion of deuterium equals <i>E</i> = 26.4 kJ/mol. The solubility of deuterium in Pd<sub>81</sub>Pt<sub>19</sub> alloy at 278.2 K was measured by volumetric method. The influence of self-stresses on diffusion of deuterium was investigated by determination of diffusion coefficients for the Pd<sub>81</sub>Pt<sub>19</sub> membrane with different initial contents of deuterium at 278.2 K. <p>
