为研究船用双堆质子交换膜燃料电池(PEMFC)功率分配方式、热管理系统布置形式对热管理系统性能影响,基于AMESim软件建立了船用双堆PEMFC系统仿真模型,根据试验数据验证了仿真模型的可靠性.在此基础上,以串联式、并联式与旁通式热管理系统模型为研究对象,研究在变载工况下采用功率平均分配、逐级分配策略对电堆进出口冷却水温差的影响规律,最后比较在功率平均分配策略下3种热管理系统布置形式的性能.结果表明,3种热管理系统中电堆进出口冷却水温差均会在不同程度上受到功率分配策略的影响,在功率平均分配策略下,采用串联式热管理系统布置形式更有利于提高电堆内部温度一致性.
Analysis of thermal management effect with power distribution strategy on marine dual-stack fuel cell
In order to study the influence of power distribution strategy and thermal management system layout on the performance of the thermal management system of marine dual-stack proton exchange membrane fuel cell(PEMFC),a simu-lation model of the marine dual-stack PEMFC system is established based on AMESim software,and the reliability of the simulation model is verified according to the test data.On this basis,the series,parallel and bypass thermal management sys-tem models are taken as the research object,the influence mechanism of the average power distribution and daisy chain dis-tribution strategies on the temperature difference of the inlet and outlet cooling water of the stack under variable load condi-tions is studied.Finally,the performance of the three thermal management systems under average power distribution strategy is compared.The results show that the temperature difference of inlet and outlet cooling water in the three thermal manage-ment systems is affected by the power distribution strategy to varying degrees.Under the strategy of average power distribu-tion,the arrangement of series thermal management system is more conducive to improving the internal temperature consist-ency of the stack.
