| 1. A high-lithium carbonate electrolyte for use in a molten carbonate fuel cell comprising:
a eutectic carbonate mixture including lithium carbonate; and
an additional lithium-containing component adapted to form lithium carbonate during at least one of an initial heat up and
operation of the molten carbonate fuel cell;
wherein said eutectic carbonate mixture includes one of potassium carbonate and sodium carbonate;
wherein said high-lithium carbonate electrolyte is adapted to be stored in a cathode side of said molten carbonate fuel cell,
and wherein said additional component is adapted to react with at least one component of an oxidizing gas flowing through
said cathode side to form lithium carbonate; and
wherein said additional component comprises between 20 and 30 mol-% lithium carbonate and between 70 and 80 mol-% lithium
hydroxide.
