摘要
以质子交换膜燃料电池(PEMFC)动态系统为研究对象。首先将质子交换膜燃料电池划分为氢气动态模型、空气动态模型、电化学电压模型和温度动态模型四部分建模;其次根据系统运行要求设计控制策略:氧气化学计量比前馈控制,阴极和阳极压力差PID控制和温度滑模控制;最后应用所建立的模型和控制策略对10 kW质子交换膜燃料电池进行仿真运行分析,结果证明所设计的系统能模拟PEMFC动态系统运行。
The proton exchange membrane fuel cell （PEMFC） power generation system was studied. PEMFC could be divided into four parts for modeling： hydrogen dynamic model, air dynamic model, electrochemistry voltage modeland temperature dynamic model. The control strategies were designed according to the system operation： oxygen excess ratio feedforward control, cathode/anode pressure difference PID control and temperature sliding modecontrol. The established model and control strategies were simulated and analyzed, and the results show the established system can simulated the PEMFC dynamic system operation.
