主　　题：Activation methods Pt,Pt-alloy,and Pt-free catalysts Pt-ionomer interface Proton exchange membrane fuel cells 

摘      要：Proton exchange membrane fuel cells(PEMFCs)have been widely acknowledged as a significant advancement in achieving sustainable energy ***,the activation of newly established Pt-ionomer interfaces in the catalyst layer of PEMFCs can be a time-consuming and costly process to ensure proper coupling and *** order to gain valuable insights into this crucial activation process,we have conducted a comprehensive analysis and comparison of the commonly employed on-line(such as current or voltage control activation,short-circuiting activation,and air interruption activation)and off-line(including boiling or steaming,acidtreatment,and ultrasonic-treatment)activation *** findings shed light on the underlying mechanisms that contribute to enhanced performance within the catalyst layer,such as the reduction of Pt oxides and hydroxides,improved proton transport,and the reduction of“dead***,this review emphasizes the significant challenges and future opportunities that lie in further enhancing the performance within the catalyst layer through the activation process.
