Abstract

CoO/Ni composite particle was prepared from filament shape Ni particle as a cathode material for Molten Carbonate Fuel Cells (MCFCs) by a mechanical coating technique. The composite particle had the morphology consisted of aNi grain coated with fine CoO particles without changing the filament structure. Moreover, the composite cathode was successfully fabricated from theCoO/Ni composite particles by a doctor blade tape casting method. The composite cathode had homogenous porous structure with good connections of grains. It suggests that a large sized composite cathode can be fabricated by the usual tape casting technique. Also, Ni solubility of the composite cathode into (Li0.62K0.38)(2)CO3 melt at 650 degreesC in 30% CO2-70% air atmosphere was about half of that of NiO. The cathode activity and IR of the composite cathode was almost the same as that of the usual NiO cathode. As a result, it is concluded that the composite cathode can be used as a new cathode for MCFCs which achieves its high stability in the carbonate melt and thelarge sized composite cathode.
