Abstract
NiO is commonly used as the cathode for the molten carbonate fuel cell due to its stability and high electrical conductivity in molten carbonates and oxygen atmosphere. However, long-term operation of MCFC has a serious problem which is the degradation of cathode material, the so-called Ni dissolution. In the present study, we have attempted to synthesize a new alternative cathode material as Co/Nb-coated NiO cathode. The results obtained in this study suggest that the Co/Nb-coated NiO cathode can be utilized as having lower dissolution and higher cell performance than those of the pure NiO cathode.
