摘要:	本兩年期計畫針對兩大主題進行實驗測量和數值分析研究：(1)研發創新加壓型固態氧化物燃料電池(SOFC)的組裝技術和(2)測試流道尺寸效應對單電池堆性能之影響。前者工作項目有三：(1)針對壓力效應對電池性能之影響、加壓型SOFC組裝設計以及不同密封材料與技術於加壓型SOFC之適用性等三個議題作分析與彙整，並提出一完整的文獻回顧報告；(2)嚐試建立氣體洩漏率之測試平台，測試不同的密封材料或組裝技術於高溫高壓條件下之洩漏率，初期以溫度範圍(400 oC ~ 900 oC)和壓力範圍(1 atm~ 3 atm)為目標，逐步提升壓力範圍至約5 atm；(3)嚐試建立三維反應流場數值模式，並預測壓力效應對多孔電極內部的傳輸機制以及電池性能的影響。後者為流道尺寸效應與電池性能之研究，我們將以陶瓷材料(B85)或不鏽鋼材料(crofer-22-APU)，製作具有不同流道尺寸之棋盤狀流場板，並將其與電池基板組裝成單電池堆，以進行一系列的電池性能測試與阻抗頻譜量測。上年度我們已建立加壓型SOFC單電池堆性能測試平台、研究氣密技術和進行加壓型SOFC文獻回顧等，請見計畫書內容。本年度將在上年度之基礎上，全力研究壓力效應對各種性能參數的影響，如功率輸出、燃料使用率、發電效率以及阻抗頻譜等等，已完成前述之目標及工作項目，並將成果發表於國際重要SCI期刊。預期本計畫之實驗量測數據與相關學理機制之研究結果，將對於提升SOFC整體發電效率以及加速國內SOFC之研發有重要助益。 This two-year proposal focuses on two major topics using experimental measurements: (1) Studying innovative pressurized-assembling technology for planar solid oxide full cells (SOFC) and (2) measuring the scaling effects of flow channels to cell performance of a single-cell stack. The former has three working items: (1) A survey of available literatures concerning the pressure effect to cell performance of planar SOFC, the assembling designs of pressurized SOFCs, and the suitability assessment of different sealing materials applying to pressurized SOFC; (2) attempting to establish a platform for the gas leakage testing, so that different assembling designs using various sealing materials can be tested at high-temperature and high-pressure conditions (400 oC ~ 900 oC; 1 atm ~ 3 atm; gradually increasing up to 5 atm); (3) measuring the pressure effects on cell performance. The latter, the scaling effects of flow channels to cell performance, is to use the ceramic material (B85) or the stainless steel (crofer-22-APU) for making different sizes of pin-type flow interconnects. Then these interconnects are assembled with the PEN to from a single-cell stack for a series of testing and measurements using the AC impedance instrument. In the previous year, we have established a high-pressure SOFC single-cell stack testing platform, studied the gas-tight technology, and completed a survey of pressurized SOFC literatures (please see the content). Based on the already established platform, this year we plan to measure the pressure effects on various cell performance parameters, such as the power density output, fuel utilization, power generating efficiency, and impedance spectra, so that the aforesaid goal and working items can be achieved. We will write up these measuring results and publish in international archival SCI journals. Finally, these results should be useful in due course for pressurized SOFC assembling technologies currently developing in INER. 研究期間：10001 ~ 10012
