摘要：The present invention discloses a process and apparatus for removing sodiumand chloride ions from an aqueous sodium chloride solution, such as seawater or brine.The process includes electrolyzing aqueous sodium chloride to remove chloride andsodium ions in the form of chlorine gas and sodium metal. Preferably, a photovoltaicdevice, such as a triple junction amorphous silicon solar cell, provides the electricalenergy for the electrolysis. The process utilizes electrode material that facilitates theproduction of chlorine gas and inhibits the evolution of hydrogen from the aqueoussodium chloride solution. The sodium is deposited onto a metal surface having a highhydrogen overpotential to produce sodium amalgam. The processed solution from theelectrolysis has a reduced sodium chloride content and may be further processed toproduce fresh water for human consumption or agricultural purposes. The sodiumamalgam is removed from the aqueous sodium chloride solution and transported to andcoupled against an air depolarizing fuel cell in water to produce electrical power with thesodium air fuel cell, power that may be used to operate the apparatus or other
machinery. The product of the reaction between the sodium amalgam and the fuel cell issodium hydroxide that may be reacted with the chlorine gas to produce sodiumhypochlorite.
