Tritium diffusion in palladium alloys with Pt and Cu

Low-temperature H2 and N2 transport through thin Pd66Cu34Hx layers

“…Thus we estimate DH 0 H ¼ À8 kJ mol À1 for the molar enthalpy of hydrogen dissolution in Pd 66 Cu 34 . Activation energies are available for the diffusion of different hydrogen isotopes in selected fccPdCu alloys [11,[26][27][28]. From a graphical presentation of hydrogen diffusion coefficients in Pd 47 Cu 53 given by Völkl and Alefeld [11], a value can be derived very similar to the E D = 33 kJ mol À1 obtained by Zetkin et al for deuterium diffusion in the same alloy [26].…”
