Electrochemical methods have been used to measure the solubility and diffusivity of hydrogen in amorphous $Ni sb{60}Zr sb{40}$ over a wide range of hydrogen concentrations. It is found that Sievert's law is not obeyed and that the concentration of hydrogen in the metallic glass varies as $P sp{1/4}$, P being the pressure of hydrogen. In the concentration range of hydrogen measured, the diffusion constant of hydrogen increases by more than a factor of ten. A Gaussian distribution of hydrogen binding energy was used to explain the concentration dependence of chemical potential. A possible explanation to the concentration dependence of diffusion coefficient was also given.
