PURPOSE:To make it possible to prevent the leakage of reaction gas almost perfectly by impregnating a metallic salt aqueous solution to the end of a porous electrode, after that, firing it to make into a metal oxide, and filling the pores of the metal oxide by the volume expansion. CONSTITUTION:On both sides of a molten carbonate electrolyte layer 1, a pair of porous electrodes 2 and 2' are arranged, and plural unit cells with the same shape of electrolyte layer 1 and porous electrodes 2 and 2' are superposed through conductive separators 3 furnishing gas feeding routes 5 and 5' crossing square each other to compose a molten carbonate fuel cell, and at the ends of the porous electrodes 2 and 2', a metallic salt aqueous solution is impregated. After that, they are fired to make into a metal oxide, and the pores of the electrodes are filled to form end seals. Therefore, since at the ends of the electrodes, a metallic salt aqueous solution is impregnated, and then fired to make into a metal oxide to fill the pores by its volume expansion, the sealing property can be improved remarkably. |
