包含离心式空压机的大功率PEMFC空气系统喘振研究
|
摘要
实验研究大功率质子交换膜燃料电池(PEMFC)低功率运行时,离心式空压机在不同工作环境下空气参数的变化和喘振规律。在空气系统模型的基础上,针对不同背压和空压机转矩条件调整防喘阀的开闭,研究空气流量与压力的变化。研究表明,PEMFC低功率运行时,离心式空压机的喘振状态随背压增大而增大,喘振阀有利于消除喘振;该文提出合理的防喘阀选取方法,依据实际系统选取相应的防喘阀能有效消除喘振并提高效率,可为下一步优化空气系统控制策略奠定基础。
The study researches air parameter changes and surge rules of the heavy duty proton exchange membrane fuel cell(PEMFC)with a centrifugal compressor working in low power operation under different working conditions.On the basis of the air system model,the changes of air flow and pressure was studied according to the different pressure and air compressor torque and the open and close of the anti-surge valve.Research showed that when PEMFC works in low power operation,the surge of centrifugal compressor become more obviously with the back pressure increases,and the surge valve is conducive to the elimination of surge.This study put forward a reasonable anti selection method of surge valve,and the suitable anti surge valve can effectively eliminate surge and improve efficiency based on actual system selects.This lay the foundation for further optimization of air system control strategy.
