High performance electrolyte for molten carbonate fuel cells comprising carbonate electrolyte doped with additive material(s) and lithium precursor(s)

摘要

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, the 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 the additive materials include one or more of Rb₂CO₃, Cs₂CO₃, BaCO₃, La₂O₃, Bi₂O₃, Ta₂O₅ and mixtures thereof, and a second carbonate electrolyte stored in at least the cathode current collector, the second carbonate electrolyte having a composition that is the same or different from the first carbonate electrolyte.
