Sol-gel LiCoO2 Coated Cathode for Molten Carbonate Fuel Cells

doi:10.3724/SP.J.1077.2006.00420

Abstract

Abstract: Sol-gel technique was employed to apply LiCoO₂ coating to the state-of-the-art cathode of molten carbonate fuel cells. The effect of LiCoO₂ coating on the NiO dissolution in eutectic Li₂CO₃-K₂CO₃ molten carbonate, single cell performance and the Ni precipitation in electrolyte matrix was investigated. The results show that LiCoO₂ coating can effectively reduce the solubility and dissolving ratio of NiO in Li₂O₃-K₂CO₃ molten salt, enhance the performance of the single cell, and inhibit Ni precipitation in the electrolyte matrix to certain extent.

Key words: NiO dissolution, LiCoO2, cathode, molten carbonate fuel cells
