碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 96 === Global dependence on fossil fuel has produced increasingly alarming energy and pollution trends worldwide , The need to speed up development of new technologies to make renewable and clean energy feasible alternatives is apparent and urgent in every nation. Fuel cell , with high energy efficiency and clean emissions , represent a promising type of clean energy , Since the conversion of the fuel to energy takes place via an electrochemical process is clean , quite and highly efficient , more efficient than fuel burning . It is the future major reliabile energy technology . 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 SOFC and MCFC cogeneration system as a major topic . It can analyze the fuel cell cogeneration system , and explain the performance of 1st and 2nd efficience law , and discuss exergy and energy diversity of devices by 2 dimensions coordinate system . Eventually , to develop an optimum design of high efficiency fuel cell cogeneration system.
