摘要
空气供应系统是大功率质子交换膜燃料电池(PEMFC)系统的核心之一,合适的空气流量和压力控制可以提高系统工作效率和稳定输出功率,同时提高耐久性。作者针对改善空气流量和压力协同控制的动态性能,提出了一种基于前馈PID的空气质量流量和压力控制策略,进行了离线仿真测试并将其应用于86 kW级燃料电池发动机,并在不同的负载需求下进行实验。结果表明,空气流量和阴极入口空气压力对比参考值均有较短的瞬态响应时间和稳定的跟随效果。
The air supply system is one of the cores of a high-power proton exchange membrane fuel cell(PEMFC)system,and proper air flow and pressure control can improve the system efficiency and stabilize the output power while improving the durability.In this paper,a feed-forward PID-based air mass flow and pressure control strategy is proposed for improving the dynamic performance of air flow and pressure cooperative control,which is tested in offline simulation and applied to an 86 kW-class fuel cell engine and experimented under different load demands.The results show that both air flow rate and cathode inlet air pressure have short transient response time and stable following effect compared to the reference values.
