A flat tubular segmented-in-series (SIS) solid oxide fuel cell (SOFC) was fabricated using decalcomania paper. The performance of a two-cell stack with 4.5-mm-wide electrodes was investigated in a temperature range of 650-800 °C. The decalcomania paper allowed fabrication of the SIS-SOFC on all sides of the flat tubular support and achieve an effective electrode area larger than that obtained using typical SOFC fabrication techniques such as screen printing or slurry coating. SEM observations revealed that each component layer was flat, uniformly thick, and well adherent to adjacent layers. Measured values of open circuit voltages were very close to the theoretical values; confirming that the processing technique utilizing decalcomania paper is suitable for SIS-SOFC fabrication. The power densities of the two-cell-stack were 437.4, 375.6, 324.6, and 257.1 mW cm−2 at 800, 750, 700 and 650 °C, respectively. [ABSTRACT FROM AUTHOR] |
