Research progress on humidification strategy of proton exchange membrane fuel cell
摘要
Abstract
PEMFC(proton exchange membrane fuel cell)is known for its advantages,which include high efficiency,high power density,cleanliness and pollution-free operation.It also offers a long working life,operates at low temperatures,and provides stable performance.Water management receives extensive attention as one of the critical technologies of the proton exchange membrane.The proton exchange membrane in PEMFC requires maintenance of appropriate humidity during use to ensure high proton conductivity and durability.Consequently,an appropriate humidification strategy is necessary to maintain the proton exchange membrane in a suitable hydration state.The humidification strategies for fuel cells are broadly categorized into internal and external humidification.Internal humidification is further divided into chemical and physical methods,while external humidification includes bubbling humidification,direct water injection,enthalpy wheel humidification and membrane humidification.The working principle and performance of each humidification method were introduced,and the characteristics of different techniques were analyzed.Based on this,the applicability and efficiency of each process in specific application fields were identified,and a reference was provided for integrating with specific application scenarios.In general,the future development of PEMFC humidification technology may mainly focus on constructing low-temperature self-humidifying membrane electrodes,the synergistic application of self-humidifying and external humidification technology,and the control optimization of the humidification process.关键词
