Abstract
In a fuel cell stack utilizing an alkali metal electrolyte, the electrolyte is distributed in parallel between the electrodes of a plurality of fuel cells and is then fed to regenerator cell which converts carbonate ions to molecular CO.sub.2 gas which is discharged from the cell. Regeneration is effected through the establishment of a hydroxyl ion gradient within a regenerator cell. The regenerated electrolyte is then returned to the fuel cells. In this manner a carbonate buildup in the cells is prevented.
