ABSTRACT:
Reduction of electrode metal dissolution in electrolyte between two metal electrodes of a voltaic cell by adding an electrode metal dissolution reduction agent to the electrolyte prior to operation of the cell, the electrode metal dissolution reduction agent being a sacrificial electrode metal, a metal promoting common ion effect with one of the electrode metals, seed metal particles serving as precipitation sites for an electrode metal, and combinations thereof. Reduction of the electrode metal dissolution in the electrolyte of a voltaic cell is also achieved by maintaining a partial pressure of carbon dioxide of about 0.5 to about 1.5 atmospheres in the electrolyte during operation of the cell. The method and electrolyte is particularly suited for molten carbonate fuel cells.
