<p>PURPOSE:To increase gas sealing capability and to decrease polarization by using an electrolyte plate in which the porosity in the part facing electrodes is low and the thickness of this part is thin and the porosity in the part facing cell frames is high and the thickness of this part is thick. CONSTITUTION:In the manufacturing process of a molten carbonate fuel cell formed by pressing electrodes 1a, 1b, and cell frames 4a, 4b against an electrolyte plate 6, the electrolyte plate 6 in which the porosity in the part facing the electrodes 1a, 1b is low and the thickness of this part is thin, and the porosity in the part facing the cell frames 4a, 4b is high and the thickness of this part is thick is used. Since the part to be in contact with the cell frames 4a, 4b of the electrolyte plate 6 is thick, the cell frames 4a, 4b are in contact with the electrolyte plate at first, and since the porosity of this part is high, this part is relatively soft and deforms easily by tightening pressure. With the advance of tightening, the electrolyte plate 6 is also in contact with the electrodes 1a, 1b. Since the electrodes 1a, 1b, and the cell frames 4a, 4b are in contact with the electrolyte plate under suitable tightening pressure, gas sealing capability is increased, and polarization is decreased.</p> |
