摘要
为了将固体氧化物燃料电池(SOFC)应用于密闭空间,首先基于Matlab/Simulink软件构建了SOFC一维分布式集中参数数学模型,并进行了仿真;其次,根据SOFC测试系统实验结果对SOFC的性能进行验证,得到了固体氧化物燃料电池的效率曲线、极化曲线、不同氧氮比时的伏安特性及效率曲线,从而确定了电池最佳工作效率点;再次,根据实验结果和仿真数据确定了电堆的最佳工作温度,并通过电炉加热和水冷却系统实现了电堆热管理;最后,研究了不同氧氮比对电池性能的影响。结果表明:提高氧氮比能小幅提升电效率。
In order to apply solid oxide fuel cell (SOFC) in confined space, a one-dimensional distributed lumped parameter mathematical model of SOFC is built based on Matlab/Simulink software. The performance of SOFC is studied through computer simulation and the experiment results of 1kW SOFC test system. The efficiency curves, polarization curves, volt ampere characteristics and efficiency curves at different oxygen and nitrogen ratios are obtained whereby the optimum efficiency of the fuel cell was determined. The optimum operating temperature of the stack is determined according to the experimental results and simulation data, and the thermal management of the reactor is realized through electric furnace and water cooling system. Study of the effect of different oxygen-nitrogen ratio on the performance of the fuel cell indicates that improvement of oxygen-nitrogen ratio can slightly increase the electrical efficiency, which has some guiding significance for the application of solid oxide fuel cell in submarine.
