摘　　要：本文提出集成带吹扫气OTM的常压CO_2零排放SOFC复合动力系统,Aspen plus模拟结果表明,集成带吹扫气OTM的常压CO_2零排放SOFC复合动力系统效率达58.59%,比相同条件下集成传统深冷空分系统的基准零排放系统(57.40%)高1.19个百分点。此外,本文还对OTM膜两侧氧气分压比,OTM温度及电池燃料利用率进行分析,探讨其对系统性能影响的规律。本文研究成果为进一步研究高效CO_2零排放SOFC复合动力系统提供有益参考。A zero CO2emission atmospheric pressure SOFC hybrid power system integrated with oxygen ion transport membrane （OTM） using CO2 as sweeping gas is proposed. The simulation result obtained by Aspen plus shows that the efficiency of the zero CO2emission atmospheric pressure SOFC hybrid power system integrated with OTM using CO2 as sweeping gas is around 58.59%, which is 1.19% higher than that of the benchmark system integrated with the traditional cryogenic air separation unit （ASU） in the same condition（57.40%）. In addition, the effects of the pressure ratio between the two sides of OTM, operating temperature of OTM and the fuel utilization factor of SOFC on the performance of new system are investigated. The research achievements from this paper will help for further study on zero CO2 emission SOFC hybrid power system with higher efficiency.
