The morphology and conductivity of a CoO-NiO composite cathode for use in a molten carbonate fuel cell (MCFC) were studied. A composite powder consisting of Ni particles covered with fine CoO particles, was used as the starting material. Conductivity of the CoO-NiO composite cathode was improved by addition of MgCO3 and reached the same level as that of a conventional NiO cathode. Moreover, the CoO-NiO composite cathode sintered at 950degreesC had better porous morphology with porosity of 66% and average pore size of 6 mum, and its cathodic polarization was almost same as that of the conventional cathode. Therefore, we conclude the CoO-NiO composite cathode is a candidate for use in new MCFC cathodes.
