摘　　要：With the global energy transformation,hydrogen energy will undoubtedly become one of the important energy sources in the future.The ocean is the largest hydrogen mine on Earth,and seeking water from the ocean is an important direction for future hydrogen energy development.However,the composition of seawater is very complex,containing over 90 chemical elements,as well as a large number of microorganisms and suspended particles,resulting in many technical bottlenecks and challenges such as harmful corrosiveness and toxicity,catalyst deactivation,and low electrolysis efficiency.For this reason,two different technology roadmaps of direct hydrogen production from seawater and indirect hydrogen production from seawater have been formed[1].Seawater indirect hydrogen production is essentially freshwater hydrogen production.Currently,large-scale demonstration projects have been conducted in many countries,such as the PosHYdon Offshore Green Hydrogen Pilot Project of Netherlands[2],the Brande Hydrogen Wind Power Hydrogen Pilot Project of Siemens Gamesa[3],and the Tracebel Overdick Offshore Wind Power Hydrogen Production Platform Project of Germany[4].However,this type of technology relies heavily on large-scale desalination equipment,with complex processes and occupying a large amount of land resources,further increasing the cost of hydrogen production and the difficulty of engineering construction.Since the concept of direct electrolysis of seawater for hydrogen production was proposed in the 1970s[5],research teams from Stanford University[6],Nanyang Technological University[7],Dalian University of Technology[8],Technical University of Berlin[9]and others have performed a lot of exploration and research around catalyst engineering,membrane material science,etc.However,up to the present,there is still no breakthrough theory and principle to completely avoid the impact of complex components of seawater on the electrolytic hydrogen production system,which has become a global problem for nearly half a century.
