Renewable energy conversion technologies that utilize hydrogen energy,such as fuel cells and water electrolyzer to produce hydrogen,play a key role in the target of carbon dioxide emission peak and carbon neutrality.Bipolar membrane fuel cells and bipolar membrane water electrolyzer are new electro-chemical energy conversion devices that use bipolar membranes as electrolytes and have been proposed in the past decade.Starting from the water dissociation mechanism of bipolar membranes,this article intro-duces the composition,interfacial layer structure and preparation process of bipolar membranes in detail,and reviews and prospects the applications of bipolar membranes in different fields.Among them,the do-mestic and abroad research progress of bipolar membranes in the fields of fuel cells and water electrolyzers is mainly introduced,and the unique advantages of application brought by the bipolar membrane structure as well as the key issues and prospects for application are summarized.
