摘要

固體氧化物電解池（Solid Oxide Electrolysis Cell, SOEC）是一種透過水蒸氣電解反應來生產氫氣的電化學技術，能將不穩定的可再生能源轉化為氫氣，未來可實現大規模與季節性儲能用途，是實現碳中和目標的關鍵手段之一，本研究主要針對高溫固體氧化物電解產氫系統模擬技術進行探討與研究。本研究主要依據SOEC實際運行特性，建立了電解過程電化學模型與熱力學模型，並通過與文獻驗證，證實所建立之模型有效性；透過使用Matlab/Simulink分析模組所建立之熱力學分析模型，比較溫度效應、氫氣／水蒸氣比例效應與熱源供應方式對於系統性能與效率的影響，發現本研究所建立之SOEC系統模型其最高效率可達79.05%。

In this paper, the simulation is applied to simulate the high-temperature solid oxide electrolysis hydrogen production system. Based on its actual operating characteristics, an electrochemical model and a thermodynamic model of the electrolysis process were established, and the effectiveness of the model was verified by comparing with experimental data. At the same time, the effects of current density and operating temperature on the polarization loss of high-temperature solid oxide electrolysis were analyzed. In addition, the commercial software Simulink/Thermolib is used to simulate the changes in the thermodynamic properties of each component in different system configurations, and is used as a preliminary simulation analysis tool for the high-temperature solid oxide electrolysis hydrogen production system.
