Abstract

1,213,777. Separating carbonates from hydroxides. VARTA A.G. 12 May, 1969 [14 May, 1968], No. 24152/69. Heading C1A. [Also in Division H1] Potassium and/or sodium carbonates may be separated from the alkaline electrolytes of fuel cells by passing the carbonate containing electrolyte over solid potassium and/or sodium metal hydroxide. It is preferred that a storage vessel containing the solid hydroxide be connected to an electrolyte circuit when the carbonate level in the electrolyte reaches for example 2 moles of carbonate per 4 moles of hydroxide. The carbonate free hydroxide leaving the storage vessel is preferably mixed with fresh fuel (e.g. methanol) and water and returned to the electrolyte circuit. Oxygen is fed to the fuel cell along with electrolyte either in the form of air or derived from the decomposition of H 2 O 2 wherein the resulting water may be used to dilute the carbonate free hydroxide.
