摘　　要：为提升质子交换膜电制氢系统在波动可再生能源输入下的制氢效率,提出面向最大效率的质子交换膜电制氢系统最优压强运行模式。介绍质子交换膜电制氢系统,提出基于压强控制的协调运行原理;对质子交换膜电制氢系统的压强特性和功率特性进行建模,从而建立面向最大效率的压强优化模型。在波动电流输入算例下检验最优压强运行模式的制氢效果,结果表明,相较于恒定压强模式,最优压强运行模式下的质子交换膜电制氢系统平均制氢能耗得到有效降低,系统性能得到明显提升。In order to enhance the hydrogen production efficiency of proton exchange membrane water electrolysis system under the input of fluctuating renewable energy,an optimal pressure operation mode of proton exchange membrane water electrolysis system aiming at maximum efficiency is proposed.The proton exchange membrane water electrolysis system is introduced,and the coordinated operation principle based on pressure control is proposed.The pressure and power characteristics of proton exchange membrane water electrolysis system are modelled,thus a pressure optimization model aiming at maximum efficiency is established.The hydrogen production effect of optimal pressure operation mode is verified under a fluctuating current input example,and the results show that,compared with the constant pressure mode,the average hydrogen production energy consumption of proton exchange membrane water electrolysis system is effectively reduced under the optimal pressure operation mode,and the system performance is significantly improved.
