    摘要： A hydride gas of metal M 1 is generated in an electrochemical cell, comprising a cathode comprising metal M 1 a sacrificial anode comprising metal M 2 , an initial concentration of aqueous electrolyte solution comprising a metal hydroxide M 3 OH. The sacrificial metal anode is electrochemically oxidized in the presence of the aqueous electrolyte solution to form a metal salt, and the metal M 1 of the cathode is reduced to form the hydride gas of metal M 1 . A starting concentration of M 3 OH in the electrolyte solution is chosen that is in the range of at and within 5% less than a predetermined maximum concentration of M 3 OH. This maximum concentration of M 3 OH is determined by determining, for various starting concentrations of M 3 OH, the solubility profile curves of the metal salt as the M 3 OH is consumed and the metal oxide is formed; and determining a maximum concentration of M 3 OH that, as it is consumed, does not yield a concentration of metal salt that precipitates out of the electrolyte solution.
