Abstract
This invention is an apparatus and a method for continuously generating a hydride gas of Mwhich is substantially free of oxygen in a divided electrochemical cell. An impermeable partition or a combination of an impermeable partition and a porous diaphragm can be used to divide the electrochemical cell. The divided electrochemical cell has an anode chamber and a cathode chamber, wherein the cathode chamber has a cathode comprising M, the anode chamber has an anode comprising Mand is capable of generating oxygen, an aqueous electrolyte solution comprising a hydroxide MOH partially filling the divided electrochemical cell. Hydride gas generated in the cathode chamber and oxygen generated in the anode chamber are removed through independent outlets. Mcan be selenium, phosphorous, silicon, metal or metal alloy, Mis metal or metal alloy suitable for anionic oxygen generation, and Mis NHor an alkali or alkaline earth metal.
