摘要

台灣地區為四周環海國家，海水淡化可供應逐漸缺乏的淡水資源。海水淡化方法中以RO逆滲透淡化技術之能源消耗量低，工程施作簡單等優點，已被世界各國大量採用。另一方面，生質物氣化產氫技術具有高轉化效率，應用於燃料電池系統可成為高能源效率、低污染之生質氫能燃料電池系統。
高溫型燃料電池可同時輸出電力與排熱，若利用於RO整合膜海水淡化系統，勢必可發揮最佳系統效益。故本論文針對生質氣化/高溫燃料電池混元技術與海水淡化整合系統作為研究主題，以淡水產量、能水轉化率(EWR)，系統性能係數COP為參數，比較兩種生質能燃料電池系統應用在海水淡化系統之性能表現，以期發展出高效生質氫能燃料電池熱/電/淡水共生系統之最佳設計規劃。

Taiwan is surrounded by sea, therefore desalination technology can supply fresh water resources lacked gradually. In the desalinization methods, the reverse osmosis (RO) technology has several advantages, such as low energy consumption and simple engineering, so it is adopted by the countries all over the world gradually. On the other hand, the hydrogen production from biomass gasification has high conversion efficiency, and it can be utilized on biomass hydrogen energy fuel cell system for high-energy efficiency and low contamination.
High temperature fuel cell can produce electricity and release heat simultaneously. If the produced electricity and released heat can be utilized on reverse osmosis intergrated membrane desalination system, the system can develop the best performance. Therefore, this thesis concentrates on the hybrid system of biomass gasification, fuel cell and desalination technology as a major topic. In order to analyze the biomass gasification combined with fuel cell and desalination systems, we will state the performance of biomass energy fuel cell on desalination system application, by using fresh water production, energy-water ratio (EWR), and coefficient of performance (COP) as design parameters, to develop an optimum design of high-efficiency biomass energy fuel cell/desalination cogeneration system.
