ABSTRACT:
The present invention relates to a cathode, which can be used in molten carbonate fuel cells (hereinafter, referred to as an "MCFC"), and a process for preparing the same. In such a cathode, NiO, which is inexpensive and has relatively good electrochemical performance, has been mainly used. However, NiO has a relatively large solubility in electrolytes of an MCFC which causes the cells to be short circuited, thereby shortening the life of the cells. However, according to the present invention, a cathode having a longer life than common cathodes for MCFC can be prepared by adding alkaline earth metal oxides, which are basic substances, to NiO, the main material of the cathodes, or impregnating an Ni plate with a solution of the alkaline earth metal oxides, to reduce the solubility of the NiO while maintaining its performance as the cathode.
