Patent ID: 8557468

Claim:
A high-performance carbonate electrolyte for use in a molten carbonate fuel cell comprising a cathode electrode, an anode electrode, an electrolyte matrix and at least a cathode current collector abutting said cathode electrode, said high-performance carbonate electrolyte comprising: a first carbonate electrolyte stored in at least the cathode electrode of the molten carbonate fuel cell comprising a mixture of eutectic Li/Na carbonate electrolyte doped with one or more additive materials and one or more lithium precursors, wherein said additive materials include one or more of BaCO 3 , La 2 O 3 , Bi 2 O 3 , Ta 2 O 5 and mixtures thereof; and a second carbonate electrolyte stored in at least said cathode current collector, said second carbonate electrolyte having a composition that is the same or different from the first carbonate electrolyte.
