PURPOSE:To prevent the cracking of an electrolytic plate by thermal shock and improve the reliability of a cell by holding the temperature of the cell at a temperature less than the coagulation point of electrolyte and of 290 deg.C or more. CONSTITUTION:At the time of stopping a molten carbonate fuel cell, the temperature of the cell is held within the range from less than the coagulation point of electrolyte to 290 deg.C or more, desirably 350 deg.C-290 deg.C, whereby the cracking by heat cycle property is perfectly prevented, and the working property at stopping is never lost. The deterioration of cell performance by the hydration and moisture absorption of lithium aluminate used as an electrolyte holding material is prevented. |
