Abstract:	本研究針對可逆質子傳導型陶瓷電化學儲能電池複合系統(Reversible Protonic Solid Oxide Electrochemical Cell, Re-PSOC)進行分析。根據電化學理論利用Matlab計算燃料電池之性能曲線，並將電化學模型鑲嵌於商用軟體Thermolib中進行系統模擬。本研究建立Re-PSOC電化學模型，研究電池在不同孔隙率、導電度、陰陽極及電解質厚度對電化學性能之影響，探討各項電池參數對電池性能的敏感度。為探討試驗電池級別升級為單電池之濃差效應，本研究建立二維通量模型進行氣體濃度之模擬，探討在不同溫度、氣氛及流量對電池性能之影響。並將二維通量模型模擬之電池性能曲線與本研究製作之Re-PSOC模型結合，從中分析在穩態及相同功率的情況下之熱力特性，並分析在燃料電池模式及電解產氫模式下之兩套系統。;This study analyzes the reversible protonic solid oxide electrochemical cell (Re-PSOC) composite system. According to the electrochemical theory, Matlab is used for theoretical/computational performance analysis of the fuel cell, and the electrochemical model is embedded in the commercial software Thermolib for system simulation. The Re-PSOC electrochemical model is established to study the effects of porosity, conductivity, thickness variation of components on the electrochemical performance of the battery. Also, the sensitivity of various battery parameters on the performance of battery in the largescale establishment is also analyzed theoretically. A two dimensional flux model is established in single cells to analyze the concentration effect of single cells. The concentration of gases, impact of various temperature, various fuels and flow rates on the performance of Re-PSOC and battery is analyzed in this study. Simulations are performed in fuel cell and electrolysis mode to analyze the thermodynamic characteristics of all the system in the steady state and same power mode.
