Abstract
A method of the type where a brine solution is converted to an alkali metal hydroxide solution within a diaphragm cell, and the resulting cell liquor from the diaphragm cell is introduced to one or more fuel cells for the conversion of the alkali metal hydroxide to form electricity, the improvement comprising regulating the conversion of alkali metal hydroxide within the fuel cell to a conversion of less than 90%, and then subsequently concentrating the alkali metal hydroxide concentration from the anolyte stream of the fuel cell.
