A kW scale molten carbonate fuel cells stack was developed and 800 hours' operating test and some performance experimental research had been done. Utilizing domestic materials completely, we developed NiO cathode and Ni Al anode with the active area 336cm 2 and γ LiAlO 2 electrolyte tile and bipolar plate with the area 900cm 2. The stack was set up with thirty cells, with 62%Li 2CO 3+38%K 2CO 3 as its electrolyte. During the 800 hours' continuous operating, the performance of the stack was stable. With 99 7%(mole fraction) H 2 as fuel and O 2 (from air) as oxidant, the average operating voltage of a cell was about 0 72 V. The maximal current density attained to 165mA/cm 2, and the maximal output power attained to 1080 W. The whole performance of the stack approached to the international level in the early 90's. This paper had given the main study works and experiments results.
