一个创新的多联产工厂驱动的固体氧化物燃料电池单元被认为是在这个细致的检查。所表达的植物的可扩展性被证实与关于经济，热力学和环境的概念作为最有效的设备运行评估的热力系统。在PEM电解槽旁采用喷射式制冷系统进行冷却和制氢。此外，热回收热交换器用于加热目的。考虑到可靠的报告，对所有子系统进行了仔细的调查和确认。结果表明，该多联产系统的冷负荷、制热量、净输出功率和H21率分别为84.421kW、2771 kW、184.21kW和1.4331kg/h。在这种情况下，第一定律效率，（火用）效率，产品总成本和环境惩罚成本分别计算为79.57%，33.92%，897.7$/G J，和0.3527$/h。此外，在所有成分中，归因于固体氧化物燃料电池模块的有效能破坏的上级部分为783.31 k W，约为总有效能破坏率的35.6%。同时，建立了一个彻底的参数评估的设置，它是说明，建议的多联产工厂的火用效率可以根据固体氧化物燃料电池单元的入口温度，压缩比，和固体氧化物燃料电池的电流密度最大化。此外，该设备的产品成本率可以通过喷射器动力流体压力、固体氧化物燃料电池入口温度和气体涡轮机出口压力来最小化。
An innovative multigeneration plant driven by a solid oxide fuel cell unit is regarded in this meticulous examination. The plausibility of the expressed plant is substantiated with regarding economic, thermodynamic and environmental concepts as the utmost efficacious equipment for operating evaluation of the thermal systems. An ejector refrigeration system beside a PEM electrolyzer are employed for cooling and hydrogen production. Furthermore, a heat recovery heat exchanger is employed for heating purposes. All subsystems are cautiously investigated and validated considering the reliable reports. The findings portrayed that the introduced multigeneration system can generate cooling load, heating capacity, net output power, and H 21 rate of 84.421 k W, 2771 k W, 184.21 k W, and 1.4331 k g/h, respectively. In this occasion, the first-law efficiency, exergetic efficiency, product overall cost, and environmental penalty cost are calculated 79.57%, 33.92%, 897.7$/G J, and 0.3527$/h, respectively. Also, among all constituents, the superior portion of exergy destruction attributed to the solid oxide fuel cell module by 783.31 k W, approximately 35.6% of the overall exergy destruction rate. Meantime, a thoroughgoing parametric evaluation of the set-up is established and it is illustrated that the suggested multigeneration plant’s exergetic efficiency can be maximized according to the inlet temperature of the solid oxide fuel cell unit, compression ratio, and solid oxide fuel cell current density. Moreover, the product cost rate of the plant can be minimized with ejector motive fluid pressure, solid oxide fuel cell inlet temperature, and gas turbine outlet pressure.
