摘　　要：利用传统化工仿真软件,构建了千瓦级固体氧化物燃料电池发电系统的计算模型,系统地研究了有无燃料再循环两种不同发电方案。结果表明:(1)额定分析工况下,若约束电堆额定燃料利用率70%,无燃料再循环发电系统交流发电功率为1 203.8 W,交流净发电效率为49.3%。燃料利用率与系统发电功率呈线性正相关性,与实验室观察测试数据吻合。(2)额定分析工况下,同样约束电堆额定燃料利用率70%,有燃料再循环发系统发电功率为1 323.3 W,交流净发电效率为53.96%。(3)电堆额定燃料利用率70%,尽管有燃料再循环发电系统能小范围提高系统的发电效率,却带来诸多实践上的弊端。有关技术路线的决策,要结合项目研发目标、研发投入、研发时间等因素进行综合评估。Two different solid oxide fuel cell systems with or without anode fuel recycling were systematically studied.Traditional chemical simulation software was used to establish the calculation model of the kilowatt-level solid oxide fuel cell system.The results show that(1)under the rated analysis condition,if the fuel utilization rate of the confined cell is 70%,the system power is 1203.8Wand the power generation efficiency is 49.3%without fuel recycling.There is a positive linear correlation between the fuel efficiency and system power,which is consistent with laboratory observation data.(2)Under the rated analysis condition,if the fuel utilization rate of the confined cell is 70%,the system power is 1323.3W and the power generation efficiency is 53.96%with fuel recycling.(3)When the rated fuel utilization rate is 70%,although the fuel recycling power generation system can improve the power generation efficiency of the system in a small range,it also has many disadvantages in engineering practice.Therefore,technical decisions should be evaluated comprehensively according to the objectives,investment and research period.
