摘　　要：建立了一个质子交换膜燃料电池电堆的冷起动模型,对燃料电池汽车的冷起动性能进行仿真,旨在通过对电堆中不同位置、不同数量的电池进行外部加热,使电堆充分利用自身的热量,以减小冷起动过程中所需的外部加热功率。结果表明,该方法可使电堆中有更多的单电池在冷起动过程中恢复工作,冷起动的时间更短,从而明显有效地提高燃料电池电堆的冷起动性能。A cold start model for proton exchange membrane fuel cell stacks is built and a simulation on the cold start performance of fuel cell vehicle is conducted,aiming at making full use of the self-heat of fuel cell stack for reducing external heating power required in cold start process by external heating on different numbers of fuel cells at different positions. The results indicate that the method used can make more fuel cells in the stack to resume functioning during cold start,shorten cold start time and hence significantly improve the cold start performance of fuel cell stack.
