开发和设计了一种循环固体氧化物燃料电池(SOFC)，用于冷、热、电三联产系统。对所设计的系统进行了技术分析，并对所提出的SOFC与两级吸收制冷机和加热系统集成的可行性进行了评估。在伊朗德黑兰的一栋教育楼(900 平方米)内对本系统的性能进行了评估。结果表明，产能为120 kW的固体氧化物燃料电池的净电能效率约为45%。混合系统的电制冷效率达到58%，电加热效率达到60%，冷热电联产系统的整体效率达到近60%。经济分析表明，尽管冷热电联产系统效率高，主要污染物显著减少，但资本回收期估计为8.3 年。
A circular solid oxide fuel cell (SOFC) is developed and designed to operate in a tri-generation system of combined cooling, heating, and power (CCHP). The designed system is technically analyzed and the feasibility of the proposed system, i.e. integration of the SOFC with a two-stage absorption chiller and a heating system, was evaluated. The performance of the presented system was assessed in an educational building (900 m2) in Tehran, Iran. It was shown that the net electrical energy efficiency of the SOFC with a production capacity of 120 kW is about 45%. The hybrid system reached an electrical-cooling efficiency of 58%, eletrical-heating efficiency of 60%, and the CCHP system reached an overall efficiency of nearly 60%. Economic analysis demonstrated that in spite of high efficiency values in CCHP system and significant reduction of the major contaminants, the capital recovery period was estimated to be 8.3 years.
