Molten carbonate fuel cell (MCFC) is the second-generation fuel cell whose operating temperature is 650°C. The 12 cm×10 cm individual MCFC was assembled, the key material, the sinter of the cell and the program of its increasing temperature were developed. The porous ceramic material of γ-LiAlO2 is used as electrolytic supporter whose thick is 0.8 mm. The distribution of the hole diameter ranges from 0.1 to 0.8μm. The porous ratio is 50%. The porous Ni plate is used as the cathode. The thickness of this plate is 0.8 mm, and the average diameter of the hole and the porous ratio are 12 μm and 55% respectively. The porous Ni plate is used as the anode. The thickness of the plate is 0.8 mm, and the average diameter of the hole and the porous ratio are 8 μm and 50% respectively. The opening-circuit voltage of the cell is 1.10 V. The current density reaches 120 mA/cm2. The output voltage is 0.65-0.70 V, and the output power is 5-10 W.
