<p>PURPOSE:To prevent the occurrence of cracks on electrolyte plates by assembling unit cells each laminated with a pair of gas diffusion electrodes and an electrolyte plate impregnated with an electrolyte on both sides then heating them to the operating temperature to fill the electrolyte in the electrolyte plate. CONSTITUTION:A mixture of an electrolyte, a holding material, alkaline earth metal carbonate, and an organic binder is molded to form an electrolyte plate. This electrolyte plate impregnated with the electrolyte on both sides and a pair of gas diffusion electrodes are laminated to form a unit cell. Inter- connectors are inserted between the unit cells and assembled, then they are heated to the operating temperature. During this heating process, pore portions are generated due to the volatilization of the organic binder in the electrolyte plates. The fused electrolyte in the gas diffusion electrodes is smoothly diffused and filled in the pore portions of the electrolyte plates. The occurrence of cracks on the electrolyte plates can be prevented, end a fused carbonate type fuel cell with no initial deterioration can be obtained.</p> |
