质子交换膜燃料电池启动策略
Start-up strategy of proton exchange membrane fuel cells
摘要
Abstract
To shorten the residence time of the H2/O2 interface and restrict the start-up voltage of the stack during the start-up process of a proton exchange membrane fuel cell ( PEMFC) , the effect differences of direct start-up, hydrogen purging time and auxil-iary load current on the performance of PEMFC were studied by experiment. A fuel system start-up control strategy was proposed which combines hydrogen-purging the anode with starting the auxiliary load current. Experimental results prove that the start-up control strat-egy limits the start-up voltage of the fuel cell, shortens the residence time of the H2/O2 interface during the start-up process of the stack, and is conducive to improve the single-battery voltage balance. So it is a kind of effective PEMFC start-up control strategy.关键词
