Summary: | Metal-supported solid oxide fuel cells (MS-SOFCs) are prepared by the high-temperature plasma spraying technique in this paper. The positive electrolyte and negative functional layers are deposited onto porous alloy substrate using thermal plasma in the air. The porous alloy supporting component is produced by molding (6 × 6 cm 2 ), pressing (35 ton), and sintering (e.g., 1000 °C, 1100 °C, 1200 °C, and 1250 °C). The 5 × 5-cm 2 MS-SOFC with an effective electrode area of 16 cm 2 shows that the open-circuit voltages are 0.95 V (Cell-1100), 1.09 V (cell-1200), and 1.08 V (Cell-1250) at 650 °C. In addition, the maximum power at a cell potential of 0.6 V is 5.7 W (Cell-1100), 11.5 W (Cell-1200), and 12.1 W (Cell-1250) at 650 °C. Thermal expansion coefficient of porous alloy supporting component is also measured in this paper. MS-SOFCs without cracking and deforming following thermal plasma spraying process have good electrical performance. Atmospheric plasma spraying method is revealed as a suitable deposition technique for manufacturing MS-SOFCs. |
