摘要

本論文主要研究固態氧化物燃料電池(Solid Oxide Fuel Cell, SOFC)核心元件-氫氣極支撐型電池之燒結製程，以及平板式電池組研製與性能提升。在電池組中，為了獲得更大之輸出，因此製造大面積的電池是必要的。然而，在製造大面積氫氣極支撐型電池時，將會在燒結過程中面臨收縮不良，以及電池翹曲的問題。因此，本研究將針對氫氣極支撐型電池燒結時產生之變形以及翹曲，定義變形率以及翹曲率，並藉由燒結時於上方施于壓重，生產出最佳變形率與翹曲率之氫氣極支撐型電池。此外, 針對平板式電池組進行結構改進，藉由降低漏氣與提高電池組性能，並堆疊為電池堆獲得更高之功率輸出。

In this thesis, studies of manufacturing processes for H 2 electrode - supported cell as well as stack development for solid oxide fuel cell (SOFC) are presented. For the purpose of attaining higher stack power output, manufacturing of large-area plannar-cell is necessary. During the manufacturing/sintering of large-area cell, un-avoided deformation and bending problems will result in difficulty/ failure during stack assembly. In this study, optimum weightings on cell sintering are concluded to minimum deformation and bending problems. Accompanied with other SOFC components-sealing, interconnectors, endplate as well as as-prepared H2 electrode - supported cell, effects of operating temperature and structure variation on stack performance (one, three, and five units) are investigated.
