摘要(中)

本研究利用靜電紡絲技術製備La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF)陰極及BaCe0.6Zr0.2Y0.2O3-δ (BCZY)電解質奈米纖維，再將兩者與傳統陰極和電解質粉末混合，製作成質子傳輸型固態氧化物燃料電池之陰極；測量不同混合參數的電池性能(極化曲線)及電化學交流阻抗頻譜，探討陰極端中氣體、氧離子、質子與電子的反應機制。
針對電化學交流阻抗頻譜進行深入分析，以瞭解不同陰極結構在質子傳輸型固態氧化物燃料電池中的反應差異，藉此了解何種材料組合能為電池性能帶來提升。此外，本研究還進行陰極氣體加濕，觀察加濕前後，電池性能的變化與電化學交流阻抗之改變，以瞭解含水氣的空氣對陰極內部反應有何影響。
使用LSCF奈米纖維與純BCZY粉末製成混合陰極時，全電池於800 ℃下測得最佳效能：開路電壓為0.93 V、功率密度峰值為212.5 mW/cm2；因LSCF奈米纖維比純粉末擁有更多和氣體反應的面積，能大幅縮短氣體擴散進入陰極之距離，更能形成氧離子與電子傳輸網路，而不受為非電子導體的BCZY電解質粉末干擾。

摘要(英)

The composite cathodes of proton-conducting solid oxide fuel cells (P-SOFC) were fabricated by mixing of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) nanofiber, BaCe0.6Zr0.2Y0.2O3-δ (BCZY) nanofiber, LSCF powder, or BCZY powder. The measurements of cell performance (I-V curve) and electrochemical impedance spectroscopy (EIS) were performed to investigate the chemical reaction mechanism between cathodes, gas, oxygen ions, protons, and electrons. Cell performance were also tested under humidified gas on the cathodes and to investigate the variations of chemical reactions.
The cell with the cathode which is composed of LSCF nanofiber and BCZY powder showed the best performance: 0.93 V for the open circuit voltage (OCV) and 212.5 mW/cm2 for the power density at 800 ℃. The LSCF nanofiber has lager reactive area for gas which can substantially reduce the distance of gas diffusion and forming the “conducting network” for oxygen ions and electrons.
