氢燃料电池系统多喷嘴氢气引射器的特性仿真与过程策略
Characteristic simulation and process strategy of multi nozzle hydrogen ejectors for hydrogen fuel cell system
摘要
Abstract
Hydrogen ejector is promising alternative to hydrogen circulation pumps due to the advantages of small volume,low cost,parasitic power free and low noise.Single nozzle ejector has limited action ranges.Therefore,a multi nozzle ejector was used to address requirements of full power and strong load variation in fuel cell systems in this study.Injection characteristics of a four nozzle ejector and physical field variation inside the stack during dynamic loading were studied using a gFUELCELL simulation modeling platform.The process strategy of a 150 kW fuel cell system equipped with a four nozzle ejector was optimized.The results show that compared with a single nozzle ejector,the four nozzle ejector can cover the operating range of 8-153 kW fuel cell stack,which achieves full coverage from idle to peak power of fuel cell systems.关键词
