摘　　要：目前,国内外能源行业正在逐渐向脱碳化转型,氢能作为新能源载体,因具有高热值、高能量密度、无污染等优点而广受关注。质子膜(PEM)电解制氢技术作为目前绿色氢能制备的主要技术之一,具有产品纯度高、响应速度快等优点。目前,PEM制氢技术根据电解槽内的操作压力分类,可分为常压PEM制氢技术和压力式PEM制氢技术,而压力式PEM制氢技术又可以根据PEM膜两侧的压力不同,分为均压式与差压式PEM制氢技术。本文介绍了各压力式PEM制氢技术的发展现状,并根据电化学原理,建立了出力为20 Nm3/h的常压式、均压式与差压式PEM电解制氢工艺流程计算模型,分析了三种PEM制氢系统一天内的产氢速率与后续氢气加压的能耗,以期为PEM电解槽技术的应用与发展提供参考。At present,the energy industry at home and abroad is gradually transforming towards decarbonization.As a new energy carrier,hydrogen energy has attracted widespread attention due to its high calorific value,high energy density,and non-polluting characteristics.Proton exchange membrane(PEM)electrolysis hydrogen production technology,as one of the main technologies for green hydrogen production,has the advantages of high product purity and fast response speed.At present,PEM hydrogen production technology is classified according to the operating pressure inside the electrolyzer,which can be divided into atmospheric pressure PEM hydrogen production technology and pressure-type PEM hydrogen production technology.The pressure-type PEM hydrogen production technology can be further divided into equal pressure type and differential pressure type according to whether the pressure on both sides of the PEM membrane is the same or not.This article introduces the current development status of various pressure-type PEM hydrogen production technologies,and establishes a calculation model for the process flow of atmospheric,pressure-equalizing,and differential pressure PEM electrolytic hydrogen production with an output of 20 Nm3/h based on electrochemical principles.It analyzes the hydrogen production rate and subsequent energy consumption for hydrogen pressurization within one day for three PEM hydrogen production systems,aiming to provide a reference for the application and development of PEM electrolyzer technology.
