摘　　要：针对大面积熔融碳酸盐燃料电池及其大功率电堆本体开发过程中关键材料的制备以及匹配特性难题,开发了大面积熔融碳酸盐燃料电池隔膜和电极的制备方法,提出了10 kW级熔融碳酸盐燃料电池堆的组装与测试运行方法。组装并运行了120节、每节电池有效面积为0.2 m^(2)的10 kW级MCFC电堆,恒电压放电测试中,最大输出功率达16.51 kW,电流密度大于95 mA/cm^(2)。通过多次试验研究与分析,获得了一种有效的在线评价MCFC电解质隔膜焙烧效果的方法,使熔融碳酸盐燃料电池本体中隔膜、电极以及熔盐电解质三者形成良好的匹配,对提高MCFC电池堆组装成功率与长周期的运行寿命具有重要指导意义。电池堆本体开发及性能测试方法,将为后续更大功率的熔融碳酸盐燃料电池发电系统的开发提供有效的理论与试验指导,对推动MCFC的商业化示范推广等具有重要的意义。The preparation method of large-area molten carbonate fuel cell matrix and electrode was developed,and the assembly and test operation method of 10 kW level molten carbonate fuel cell stack was proposed in view of the difficulties in the preparation and matching characteristics of the key materials during the development of large-area molten carbonate fuel cell and its large power stack.A 10 kW class MCFC stack with 120 cells and an effective area of 0.2 m^(2) for each cell was assembled and operated.During the constant voltage discharge test,the maximum output power reaches 16.51 kW and the current density is above 95 mA/cm^(2).Through multiple experimental studies and analysis,an effective online evaluation method for the baking effect of MCFC electrolyte matrix is obtained,which makes the matrix,electrode and molten salt electrolyte in the molten carbonate fuel cell body matched well,and has important guiding significance for improving the success rate and the long cycle operation life of MCFC stack assembly.Meanwhile,the study of MCFC stack body and performance test methods will provide effective theoretical and experimental guidance for the subsequent development of larger power molten carbonate fuel cell power generation system,and have important significance in the commercial demonstration and promotion of MCFC.
