基于AMESim的燃料电池系统低温起动仿真

Simulation of cold start of fuel cell system based on AMESim

当前燃料电池汽车受到越来越多的关注,而燃料电池汽车商业化前还有很多问题亟需解决,其中燃料电池系统低温起动便是一个重点难题。使用AMESim软件建立了一个燃料电池一维系统模型,针对燃料电池系统恒电压和恒电流低温起动过程进行了研究。研究发现,较低的起动电压和较高的起动电流更有利于低温起动过程,且恒电压起动比恒电流起动更具优势。

Nowadays, increasing attention is paid to fuel cell vehicles, but there are many problems to be solved before the commercialize of fuel cell vehicles, and the cold start process of the fuel cell systems is of great difficulty among all the problems. A one-dimensional model of fuel cell system was developed using AMESim and the potentiastatic and galvanostatic cold start process of fuel cell system was studied. The results show that the lower voltage and the higher current are beneficial to cold start, and potentiastatic cold start is superior to galvanostatic cold start.
