质子交换膜燃料电池停机策略的实验研究
Experimental Study on Shutdown Strategy of Proton Exchange Membrane Fuel Cells
摘要
Abstract
The decrease of proton exchange membrane fuel cell performance during shutdown process is mainly due to the existence of residual hydrogen in the anode side. In order to quickly eliminate residual hydrogen, two shutdown control strategies (which discharge every single fuel cell using air-cooling stack fans and auxiliary load, respectively) were proposed in this paper. Effects of three shut-down strategies including direct shut-down, overall discharging shut-down and individually discharging shut-down using auxiliary load were studied on the performance of PEMFC. The results demonstrate that the strategy proposed can shorten the time for each cell remaining under high voltage and prevent the occurrence of single cell reverse polarity during shutdown, which proves the effectiveness of the proposed strategy.关键词
