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
