The diffusion coefficient, heat of transport and solubility limit were determined by means of resistance measurements. The experiments were performed below room temperature, using H concentrations of up to 1.29at%. A very low activation energy (0.040eV) was found for diffusion. The heat of transport was 0.01eV. The solubility limit, as measured between 120 and 270K, was associated with a precipitation enthalpy of 0.13eV.
