摘　　要：针对质子交换膜燃料电池(PEMFC)供氢系统供气充分且氢压响应迅速的要求,提出了供氢系统零部件匹配设计方法。首先,采用机理和半经验建模相结合的方法建立了燃料电池氢气供应系统集总参数模型,并结合该模型提出了氢气供应系统的匹配设计方法。为验证匹配设计方法的合理性,针对一80 kW电堆进行了仿真分析。结果表明:在前馈+PI控制策略作用下,从怠速阶跃至额定工况的阳极压力上升时间为0.5 s、超调量为3 kPa;排氢扰动作用下压力波动小于0.8 kPa;额定工况引射器的引射比为2.14;泄压阀流量足以保证电堆安全运行。该匹配方法满足了供氢系统动态响应、氢气循环、安全特性的需求,为质子交换膜燃料电池氢气供应系统的选型匹配提供了理论基础。Aiming at the requirement of sufficient gas supply and rapid response to hydrogen pressure in the hydrogen supply system of proton exchange membrane fuel cell,a matching design method for the components of the hydrogen supply system was proposed.First,the method of mechanism modeling and semi-empirical modeling was used to establish the lumped parameter model of the hydrogen supply system of proton exchange membrane fuel cell,and the selection scheme of the hydrogen supply system was proposed.In order to verify the rationality of the selection scheme,a simulation was carried out for an 80kW stack.The results show that under the action of the feedforward+PI control strategy,the anode pressure rise time from the idle speed step to the rated operating condition is 0.5 s,and the overshoot is 3kPa.The pressure fluctuation under the action of hydrogen discharge disturbance is less than 0.8 kPa;The ejector ratio of the ejector is 2.14.The flow rate of the pressure relief valve is sufficient to ensure the safe operation of the stack.The matching method meets the requirements of the dynamic response,hydrogen circulation and safety characteristics of the hydrogen supply system,and provides a theoretical basis for the selection and matching of the hydrogen supply system of the proton exchange membrane fuel cell.
