Abstract
A method for generating hydride gas of metal Min electrochemical cell comprising cathode comprising metal M, sacrificial anode comprising metal M, an initial concentration of aqueous electrolyte solution comprising metal hydroxide MOH, wherein the sacrificial metal anode electrochemically oxidizes in the presence of the aqueous electrolyte solution to form metal salt, and hydride gas of metal Mis formed by reducing the metal Mof the cathode. The method also comprises steps of determining solubility profile curves of metal salt as MOH is consumed and metal oxide is formed by oxidation reaction at various concentrations of MOH; determining the maximum concentration of MOH that does not yield a concentration of metal salt that precipitates out of the electrolyte solution; and choosing a concentration of MOH that is in the range of at and within 5% less than the maximum concentration of MOH to be the initial concentration of MOH.
