综述了在简单循环中采用常压固体氧化物燃料电池(SOFC)的电力系统概念；在与燃气轮机的常压混合循环中(SOFC/GT)；在加压SOFC/GT混合循环中(PSOFC/GT)。提出并讨论了电力系统性能的估计。针对热电联产(CHP)设计的简单常压SOFC系统可以接近50%的发电效率(净AC/LHV)和80%的燃料效率[(净AC+可用热)/LHV]。采用中冷、回热和再热燃气轮机循环的加压SOFC系统发电效率接近70%，而常压SOFC/燃气轮机混合循环和简单加压SOFC/燃气轮机循环的发电效率分别接近55%和60%。这些高水平的效率是非同寻常的，因为它们可以在兆瓦级的容量水平上实现。版权所有©1999，ASME
Reviewed are power system concepts employing the solid oxide fuel cell (SOFC) at atmospheric pressure in simple cycle; in an atmospheric pressure hybrid cycle with a gas turbine (SOFC/GT); and in a pressurized SOFC/GT hybrid (PSOFC/GT). Estimates of power system performance are presented and discussed. Simple atmospheric pressure SOFC systems designed for combined heat and power (CHP) application can approach 50% electric generation efficiency (net AC/LHV) and 80% fuel effectiveness [(net AC + useful heat)/LHV]. Pressurized SOFC systems with intercooled, recuperated, and SOFC-reheated GT cycles can approach 70% electric generation efficiency, while the atmospheric pressure SOFC/GT hybrid cycle and a simple pressurized SOFC/GT cycle can approach 55% and 60% generation efficiency, respectively. These high levels of efficiency are extraordinary in that they are achievable at the MW capacity level.Copyright © 1999 by ASME
