As the demand for sustainable energy increases,the development of clean new energy systems is an effective way to solve current problems.Hydrogen peroxide(H2O2),as a new energy carrier,is easy to be stored and transported and has high energy density,which is considered as an ideal alternative to traditional fossil energy.H2O2 fuel cells can operate in an oxygen-free environment,and only produce oxygen and water during the cell operation,which can realize the real pollution-free and carbon emission-free.H2O2 has been widely used in fuel cells in recent years.Based on this background,this paper provides a systematic overview and summary of the types and development of H2O2 fuel cells,as well as an outlook on the research prospects.
