The electrochemical behavior of hydride ions at a Mo electrode in a LiBr-KBr-CsBr-LiH melt was studied by using cyclic voltammetry and chronopotentiometry. By using voltammetry and chronopotentiometry, the diffusivity of the hydride ion was found to be described by,

D (cm2/s) = 1.2 x 10-1 exp[-45000/RT]

at 523 to 673K.
