为了进一步降低固体氧化物燃料电池(solid oxide fuel cell，SOFC)复合系统回收 CO2的能耗，该文提出一个新型的集成氧离子传输膜(oxygen ion transport membrane，OTM)的 CO2零排放 SOFC 复合动力系统。利用单耗分析方法得到系统各单元的能耗分布情况，分析了SOFC的主要参数对整个系统性能的影响，并与集成传统深冷空分系统的零CO2排放SOFC复合动力系统进行了比较研究。研究结果表明：与不回收CO2的传统SOFC复合动力系统相比，与OTM集成的复合动力系统效率下降仅2.16个百分点，比与传统深冷空分系统集成的复合动力系统效率高0.74个百分点。该文研究成果可以为研究更高效的零排放复合动力系统提供有益的参考。“,” In order to further reduce the energy consumption of CO2 recovery in the solid oxide fuel cell (SOFC) hybrid system, a new zero CO2 emission SOFC hybrid power system integrated with oxygen ion transport membrane (OTM) was proposed in this paper. With the method of unit consumption analysis, the energy consumption distribution characteristics of overall system were obtained, and then the effects of key operation parameters on the overall system performance were investigated. This paper also compared the performances of the new system with the zero CO2 emission SOFC hybrid power system integrated with the traditional cryogenic air separation unit. The results show that the new system still has high efficiency after CO2 recovery. Compared with other systems, the efficiency of the zero CO2 emission SOFC hybrid power system integrated with OTM is around 64.71%, only 2.16 percentage lower than that of the traditional SOFC hybrid power system (66.87%) without CO2 capture and 0.74 percentage higher than that of the zero CO2 emission SOFC hybrid system with the cryogenic air separation unit (63.97%). The research achievements provide valuable reference for further study on zero CO2 emissions SOFC hybrid power systems with higher efficiency.
