Description

一种基于电流的排氢阀和排水阀开启频率控制方法 技术领域
本发明涉及一种排氢阀和排水阀开启频率控制方法，具体涉及一种基于电流的排氢阀和排水阀开启频率控制方法。
背景技术
燃料电池***在一定情况下可能存在湿度过大情况，且极容易产生水淹，故一般电堆或***中需集成排水电磁阀。
由于阴极长期有大量氮气存在，且在阴阳极具备一定浓度差，故一定时间，氮气将由阴极扩散至阳极，导致阳极氢气浓度下降，故需要定期排氢，保证阳极氢气浓度，从而保证电压稳定。
要同时从阳极排水、排氢比较困难，故再排水排氢之前集成分水器，提前将氢气与水分离，在分别将水与氢气通过不同的通道排出***。
关于排氢频率，现有方案多采用固定排氢频率，无法根据不同效率灵活调节排氢频率。
专利文献1公开了一种燃料电池阳极间歇排氢***及其控制方法，所述控制方法包括：实时监测燃料电池电堆的电压及所述燃料电池电堆阳极出口处的氮气浓度；当确定所述燃料电池电堆在阳极排氢关闭期间的电压压降值大于预设的压降阈值时，控制所述燃料电池电堆阳极出口的氢气开始排放；当确定所述燃料电池电堆阳极出口处的氮气浓度小于预设的氮气浓度阈值时，控制所述燃料电池电堆阳极出口的氢气排放停止。所述排氢***及其控制方法可以在维持燃料电池电堆电压的稳定性的基础上提高燃料电池***的氢气利用效率。
专利文献2公开了一种可在低温下快速开启的质子交换膜燃料电池排氢***，包括：排氢管、排氢阀、冷却液支路和注液阀，所述排氢管包括进口管路和出口管路，两者通过排氢阀相连接，进口管路的进气口与燃料电池电堆连接；排氢管的进口管路和冷却液支路通过注液阀相连接，冷却液支路的另一端可注 入冷却液。本发明利用燃料电池***冷却液凝固点低的特性，对排氢管路和排氢阀覆盖保护，避免了因气、液态水因低温凝固导致的管路堵塞和阀体冻结，显著提高了排氢***的开启速度，同时缩短了燃料电池***在低温下冷起启动的时间，提高了燃料电池***的效率，整体设计简单易于实现。
发明内容
为了解决现有技术存在的问题，本发明提供一种基于电流的排氢阀和排水阀开启频率控制方法，根据不同效率调节排氢频率，高效区间排氢频率高，低效区间排氢频率低。燃料电池的效率由电流决定，电流越大、效率越低。因此在供氢时可以根据不同电流下的电池效率控制供氢量，以及氢气循环回路的控制。
本发明的目的是通过以下技术方案实现的：
一种基于电流的排氢阀和排水阀开启频率控制方法，根据不同电流区间，分别控制排水、排氢阀的开启周期和开启时间，提高氢气利用率。其中，排氢阀开启周期在电流不同区间开启周期不同；排氢阀开启时间，在电流不同区间，开启时间不同；排水阀开启周期在电流不同区间开启周期相同；排水阀开启时间，在电流不同区间，开启时间不同。
进一步地，排氢阀开启周期在电流不同区间开启周期不同；在0～1/4I额时，开启周期为T1，在1/4I额～1/2I额时，开启周期为T2，在1/2I额～3/4I额时，开启周期为T3，在3/4I额～I额时，开启周期为T4；
其中，T1＞T2＞T3＞T4。

其中，T1＞T2＞T3＞T4＞t1＞t2＞t3＞t4。
进一步地，排水阀开启周期在电流不同区间开启周期相同，均为T0。
更进一步地，排水阀开启时间，在电流不同区间，开启时间不同。在0～1/4I额时，开启时间为t5，在1/4I额～1/2I额时，开启时间为t6，在1/2I额～3/4I额时，开启时间为t7，在3/4I额～I额时，开启时间为t8；
其中，T0＞t8＞t7＞t6＞t5。
