Magnetron　sputtering　is　an　effective　strategy　for　constructing　the　ordered　catalyst　layers　(CLs)　of　proton　exchange　membrane　fuel　cells　(PEMFCs).　However,　different　electrochemical　properties　of　CLs　are　observed　even　when　fabricated　with　similar　magnetron　sputtering　technology.　Herein,　we　proposed　a　detachable　glass　carbon　electrode　to　explore　the　effect　of　the　sputtering　fabricating　technology　on　electrochemical　properties　of　CLs.　Results　show　that　increasing　sputtering　time　or　Ar　gas　pressure　both　improve　the　Pt　loading　of　CLs,　while　increasing　Ar　gas　pressure　brings　out　the　outstanding　activity　in　electrochemical　surface　area,　and　mass　activity　of　the　ORR　of　CLs　under　high　sputtering　power.　Furthermore,　different　substrate　materials　and　post-processing　are　analyzed,　and　it　is　found　that　PANI　substrate　materials　have　a　positive　impact　on　electrochemical　properties　of　CLs　for　their　interaction　with　electrocatalysts,　but　the　annealing　treatment　could　not　enhance　the　electrochemical　properties　of　CLs.　©　2025　Hydrogen　Energy　Publications　LLC
