| 摘 要： | 针对燃料电池堆再循环管线的再循环速率低的问题,提出用于燃料电池的氢气供应系统的循环控制方案,根据再循环管线中再循环的气体量精确估计由吹扫阀吹扫的氢体浓度,通过反馈每种气体的吹扫量,调节吹扫阀的开度,提升氢气利用率,并对该方案进行仿真分析。仿真结果表明,燃料电池阳极侧氢气利用率明显提升,最高可达92.733%,可提高燃料电池堆的耐久性。

| Abstract: | Recycling pipeline for fuel cell stacks of recirculation rate low, put forward the hydrogen supply system for fuel cell cycle control scheme, according to the amount of gas recirculation in the recirculating pipeline accurately estimated by purging purge valve of hydrogen concentration, through the feedback of each gas purging, adjust the opening of the purge valve, improve utilization rate of hydrogen, and has carried on the simulation analysis to the scheme. The simulation results show that the utilization rate of hydrogen on the anode side of fuel cell is significantly improved, up to 92.733%, and the durability of fuel cell stack is improved. |
