Abstract:

Hydrogen energy has become an important strategy for global energy transformation.To achieve large-scale,long-distance,and low-cost hydrogen energy transportation,the use of natural gas pipelines for hydrogen mixed transportation has the feasibility of large-scale application.However,the hydrogen content in hydrogen doped natural gas is usually low,and hydrogen needs to be separated from natural gas before application.Electrochemical hydrogen pump technology is a hydrogen purification and compression technology that uses electricity as the driving force,membrane as the proton conduction and gas barrier medium.It has high selectivity and hydrogen source adaptability,and can simultaneously achieve hydrogen purification and compression.It is an effective way to transport hydrogen and connect with application ends.The common methods for hydrogen separation and purification were compared,and the working principle,main functions,key components,and research progress of electrochemical hydrogen pumps were introduced.The research progress of the core component proton exchange membrane was analyzed,mainly including polymer proton exchange membrane and mixed matrix proton exchange membrane.The prospects and challenges of using electrochemical hydrogen pumps for hydrogen doped natural gas separation were discussed.

Key words: hydrogen blend natural gasseparation, separation, electrochemical hydrogen pump, membrane electrode, proton exchange membrane
