太陽能製氫技術結合燃料電池發電系統之研究

鑒於再生能源與燃料電池發展正受全球矚目，加上再生能源先天具有間歇性本質及發電不穩定之問題，其造成難以普及化的原因，發展再生能源之際必須思考能源儲存議題，並能有效提出解決對策。因此本論文旨為研究太陽能製氫技術結合燃料電池發電系統之研究，其包含數位化太陽能充電系統、製氫系統(鹼性電解槽、水循環及氣液分離系統)、氫氣壓縮系統、純化系統及燃料電池發電系統。數位化太陽能充電系統之電能轉換以數位訊號處理器(TMS320LF2407)為整體系統控制核心，來達到發電系統整體之穩定性，其電能轉換效率為 80.5%；製氫系統產氫量為310c.c/min、產氫效率為70%；產氫濃度為99.2%，將壓縮後氫氣儲存於儲氫罐中作為燃料電池之進料，其發電效率為29.41%。唯有再生能源製氫技術才能擺脫傳統石化能源製氫之污染，使產氫之技術達到潔淨循環生產，完全符合了永續發展與環境保護之理念。

In view of the development of renewable energy and fuel cells are gazing at global, combined with renewable energy sources with intermittent nature of birth and generation of instability problems, it makes difficult to popularize the development of renewable energy must consider the occasion of the energy storage issues and effective proposed counter measures. Therefore, this paper aims to study the solar hydrogen fuel cell power generation system combined with the research with the research it contains several solar charging system, hydrogen production system (alkaline electrolyzes, the water cycle and the gas-liquid separation system), hydrogen compression system, purification system and fuel cell power generation system. Digital signal processor (TMS320LF2407) of digital power conversion for solar charging system for the overall system control center to achieve all stability of power system, and the power conversion efficiency is 80.5%, production capacity of hydrogen produce system 310c.c/min, 70% of produce hydrogen efficiency. The purity result was 99.2% by purification system, the compressed hydrogen stored in the hydrogen tank as fuel for high efficiency feeding, 29.41% of power generator hydrogen efficiency. Hydrogen production from renewable energy sources can only get rid of the pollution of traditional fossil energy hydrogen production cycle, it fully consistent with the concept of sustainable development and environmental protection.
