摘要： An internal reforming molten carbonate fuel cell having a membrane for intercepting carbonate vapor and hydrated vapor is disclosed. The intercepting membrane is made from nickel or nickel alloy which has a high electrical conductivity, corrosion resistant property in an anode environment, and a low affinity for the carbonate vapor. Due to the presence of the intercepting membrane, the transfer of the carbonate vapors and hydrated vapors to the internal reforming catalyst is markedly retarded to prolong the catalytic activity. As a result, a longer operating molten carbonate fuel cell can be obtained.

摘要： Disclosed is a method for in-situ preparation of a polybenzimidazole-based electrolyte membrane, including: polymerizing a polybenzimidazole polymer in a solution; casting a solution containing the polymerized polymer onto a substrate and drying the solution in air to form a membrane; washing the dried membrane with water or alcohol; and allowing water or alcohol to evaporate from the membrane containing water or alcohol, while maintaining the shape of the membrane. The method for in-situ preparation of a polybenzimidazole-based electrolyte membrane allows easy preparation of a polybenzimidazole-based electrolyte membrane having a desired area without any complicated processes, and thus contributes to simplification of an overall process for fabricating a fuel cell.

摘要： 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.
