摘要

一种致密型固态氧化物燃料电池发电系统，其包含一具有燃烧器、点火器、重组器、阴极空气预热器及阴极热空气出口单元之热工元件整合装置；一与重组器、阴极空气预热器及阴极热空气出口单元连通之气流分配单元；一与气流分配单元连通之SOFC电池堆；一与燃烧器连通之热能回收热交换器；以及一包覆热工元件整合装置、气流分配盘及SOFC电池堆之绝热保温炉。藉此，可将燃烧器产生之尾气热能进入SOFC电池堆进行加热，并以燃烧器之热辐射、热传导及阴阳极气体之热对流同时对SOFC电池堆进行加热，使其达到操作温度时而可输出电力，进而不需任何电热装置，而具有结构简单、操作灵活、增加系统效率、减少污染物之排放且设备及操作成本较低之功效。;An apparatus of power generation is provided. The apparatus uses a dense stack of solid oxide fuel cells (SOFC). The exhaust gas generated by a combustor enters into the SOFC stack for heating. Simultaneously, the SOFC stack is heated by the thermal radiation and thermal conduction of the combustor as well as the thermal convective heat transfer of gases between the anode and the cathode. Thus, the SOFC stack is heated to reach the operating temperature for outputting power without any electroheat devices. The present invention has a simple structure, flexible operation, increased efficiency, reduced emission of pollutants and lowered cost of equipment and operation.
