Kurzfassung:
A 75kW class pilot scale MCFC stack composed of 128 unit cells was assembled and operated. 10,000cm2 class MCFC stack components are also developed to fabricate the MCFC stack. The separators with the effective area of 10,000 cm2 were adopted new design concepts such as 3-piece architecture, simple channel structure, and flat mask plate to improve the gas flow behavior and wet seal performance. The electrolyte impregnated anode and cathode with the effective area of 10,000 cm2 were fabricated by the ex-situ process to enhance the reliability of the stack during the heat-treatment. Finally, the gas distribution manifold embedded light-weight stack structure was employed. The stack showed the average open circuit voltage of 1.065V that near meet theoretical one and 78.5kW DC in power output. A 125kW class MCFC stack using the same components will be assembled and started to operate by the end of 2009.
