Abstract

The relation between hydrogen pressure and the Warburg coefficient derived from AC impedance measurement at an Mo electrode indicates that hydrogen gas dissolves chemically into molten LiCl-KCl. The solubility coefficient of hydrogen in molten LiCl-KClat 673 K was estimated to be 6.1 × 10 -6 mol H cm-3 atm-1/2 from the amount of the dissolved hydrogen obtained by tensimetry. The diffusion coefficient of the dissolved hydrogen in this melt was calculated to be 2.6 × 10-5 cm2 s-1 from the Warburg coefficient and the solubility coefficient.
