Abstract
SOFC stack for residential SOFC system is improved due to cell optimization and reduction of size and weight of the stack. A power density of 1.6 W/cm2 is obtained at 0.7 V with button cell due to the cathode optimization. The cathode optimization is successfully applied to fabrication of a large cell that has an active electrode area of 100 cm2. An integrated power stack with 18 large cells shows an output power of 1.1 kW and DC power efficiency of 62 % (LHV) when the fuel utilization is 80 % in the measurement at 700 ºC with methane fuel.
