This report presents an analysis of the levelized cost of electricity (LCOE) from two integrated coal gasification fuel cell (IGFC) power plants that use solid oxide fuel cell (SOFC) technology to convert syngas to electricity. The two plants are differentiated primarily by the Fuel Cell Island technology used, one representing an atmospheric-pressure fuel cell power island, and the other a pressurized fuel cell power island combined with gas-expander power recovery. This analysis is part of an overall effort to compare the economics of fuel cell-based systems in central station and distributed generation applications. 本文從兩個方面對電力均衡成本進行了分析。 采用固體氧化物燃料電池（SOFC）技術(shù)的煤氣化燃料電池（IGFC）發(fā)電廠 把合成氣轉(zhuǎn)化為電。這兩種植物主要由燃料電池分化。 使用的島技術(shù)，一個代表大氣壓燃料電池動力島，以及 另一個是壓力燃料電池動力島，結(jié)合氣體膨脹機動力回收。這個 分析是比較基于燃料電池的系統(tǒng)在 中心站和分布式發(fā)電應用。
