【Abstract】Against the backdropofaccelerated global low-carbon transition，HydrogenFuel Cell Vehicles （HFCVs） haveatracted increasing atention asakey pathway for gren transportation.Existing studies mainly focus on development trendsandtechnologicalimprovements，whilelackingsystematicanalysisofthepaternsandevolutionarypathsof global cross-bordertechnologyflows.BasedonglobalHFCVpatentdatafrom2OoO to2O23，thisstudyconstructsaninternational technology flow network using social network analysis，andidentifies keytechnology exporters，importers，and fusion paternsthrough textvectorizationandclustering.Theresultsrevealamulti-centered，multi-tierednetworkstructureof global technologyflows.Corecountriessuchasthe United States，Japan，andGermanyplaydominantrolesintechnology difusionandas intermediary hubs，whileemerging players likeChinaand South Koreaare steadilyadvancing technological catch-upand independent innovation.Theanalysis further identifies1 major technology fusion themes，suchascore materialsandpower conversionsystems，highlighting thediversityandphasedevolutionofcross-border technological exchanges.
