논문 초록 (Abstract)
We are developing 1 kW class solid oxide fuel cell (SOFC) system for residential power generation (RPG) application supported by Korean Government. Anode-supported single cells with thin electrolyte layer of YSZ (yttria-stabilized zirconia) or ScSZ (scandia-stabilized zirconia) for intermediate temperature operation (650–750 ◦C), respectively, were fabricated and small stacks were built and evaluated. The LSCF/ScSZ/Ni-YSZ single cell showed performance of 543mWcm−2 at 650 ◦C and 1680mWcm−2 at 750 ◦C. The voltage of 15-cell stack based on 5 cm×5 cm single cell (LSM/YSZ/Ni-YSZ) at 150mW was 12.5V in hydrogen as fuel of 120 sccm per cell at 750 ◦C and decreased to about 10.9V at 500 h operation time. A 5-cell stack based on the LSCF/YSZ/FL/Ni-YSZ showed the maximum power density of 30W, 25W and 20W at 750 ◦C, 700 ◦C and 650 ◦C, respectively. LSCF/ScSZ/Ni-YSZ-based stack showed better performance than LSCF/YSZ/Ni-YSZ stack from the experiment temperature range. I–V characteristics by using hydrogen gas and reformate gas of methane as fuel were investigated at 750 ◦C in LSCF/ScSZ/FL/Ni-YSZ-based 5-cell stack.
