摘要

隨著化石燃料日益減少，加上能源需求遽增，使得世界各國積極尋求二次能源以解決能源短缺的問題。二次能源中，生質能具有取之不盡、用之不竭的特性，且含硫量約為化石燃料的百分之ㄧ，可降低空氣污染且不增加溫室氣體排放，因而為值得開發之能源技術。燃料電池具有能源效率高、不受自然環境因素影響、污染低等優點，又稱為未來能源之星。
高溫型燃料電池中，最具代表性為熔融碳酸鹽燃料電池(MCFC)和固態氧化物燃料電池(SOFC)，其適合應用於區域分散型與集中型電廠。高溫型燃料電池所排出的廢(餘)熱可再度用於氣渦輪機、蒸汽渦輪機或其他熱驅動設備，進而組成燃料電池汽電共生系統。
故本論文係針對生質能源轉化技術種類及燃料電池汽電共生系統為研究主題，藉以解析生質能源連結燃料電池汽電共生系統，將說明生質燃料應用在燃料電池汽電共生系統之性能表現，以期發展出高效生質能源燃料電池汽電共生系統之最佳設計規劃。

Due to the fossil fuel is being decreased and energy consumption is being increased, to find the renewable energy to solve the energy shortage is becoming aggressively in the world. In the renewable energy biomass energy has an unlimited resource characteristics, which only contains around 1% sulfur of fossil fuel. It can reduce the air pollution and does not increase the greenhouse gases emission, therefore, that energy technology can be developed significantly. The fuel cells have high energy efficiency and can’t be affected by the environmental factors as well as low pollution advantages, etc. It is the future major energy.
High temperature fuel cell the typical products are Molten Carbonate Fuel Cell and Solid Oxide Fuel Cell. It is suitable for district distribution and concentration power plants. High temperature fuel cell exhaust the waste energy can be used to gas turbines, steam turbines and other thermal driver equipment then combines as a fuel cell cogeneration system.
This thesis concentrates on biomass energy conversion technology and fuel cell cogeneration system as a major topic. It can analyze the biomass energy combined with fuel cell cogeneration system and explain the performance biomass fuel apply to fuel cell cogeneration system, to develop an optimum design of high efficiency biomass energy fuel cell cogeneration system.
