摘要(Abstract)：

提出一种新型集成化学链制氢的CO_2零排放固体氧化物燃料电池/燃气轮机/有机朗肯循环混合动力系统，在实现高效发电的同时，高效分离捕集CO_2。系统以甲烷为燃料，通过化学链反应产生氢气进入燃料电池，避免了电池内部积碳现象发生，电池阳极出口回路至化学链，燃料反应器出口与电池阴极出口气体进入燃气轮机做功，排气余热被有机朗肯循环系统回收利用，进一步提高系统效率；并建立了系统模型并进行热力学性能分析，得到系统性能随燃料流量、燃料利用率、电池工作温度及系统工作压力的变化规律。结果表明：系统综合能源利用效率可达74.10%以上，电效率可达62.42%以上，?效率达到57.73%；敏感性分析表明，系统工作压力达到7×10~5 Pa时，系统性能达到最优。
