We developed induction furnace brazed anode supported tubular and flat tube SOFCs to improve power density and studied basic technology of key components for making stacks from them. Performance of the flat tube cell showed 210 mW/cm 2 (0.7V, 300 mA/cm 2 ) at 750°C. Induction furnace brazing was applied to connect ceramic and metal parts and their gas permeability was tested. The results indicated that the induction furnace brazing method could be used effectively for making anode supported tubular and flat tube cell stack. Through these experiments, we obtained basic technology of such cells and established a proprietary concept of the anode-supported tubular and flat tube cell stack.
