| Outline of Final Research Achievements |
A layered micro-SOFC was fabricated and its electrochemical properties including maximum power density were evaluated. The layered micro-SOFC without defects such as mechanical cracks was successfully prepared. It showed a theoretical EMF at elevated temperatures. Cathode materials, which is compatible with an electrolyte material and enables co-sintering, were also developed. The optimized cell showed a maximum current of 6.7 mA and a maximum power of 2.17 mW. The maximum power was converted to a maximum power density of 28 mW/cm2 and an apparent maximum power density of 121 mW/cm2 by using an internal effective electrode area size and an edge area size, respectively. As a new cathode material for co-sintering, Y-doped LSMs were found to be promising.
