摘要
为了研究不同电池联接方式对混合动力系统性能的影响,应用模块化建模的方法建立了混合动力系统模型.利用该模型分析了电池的燃料和氧化剂都采用串联以及燃料串联氧化剂并联2种不同电池联接模式下燃料电池及整个混合动力系统性能的变化.将所有电池都并联的联接方式作为参考,不同联接方式的结果与参考工况进行了比较.结果表明,将电池的燃料和氧化剂都串联后电池堆可以被更好地冷却,电池堆内的温度分布更加均匀,系统的特性会有明显改善.
The model of hybrid system was built using modular modelling method to compare the effect of different connection methods on the system performance. Characteristics of fuel cell stacks and hybrid sys-tem were compared when the fuel and oxidant are both series and series fuel and parallel oxidant. The con-dition that fuel and oxidant are both parallel was viewed as an example and the comparisons between differ-ent connection methods and example were completed. The results show that the fuel cell stack can be cooled better and the temperature distributions are uniform with the fuel and oxidant are both series, so the performance of whole hybrid system is better.
