China＇s　dual-carbon　goals　have　positioned　hydrogen　as　a　central　pillar　of　its　energy　transition.　This　review　examines　the　recent　development　of　China＇s　hydrogen　supply　chain,　with　particular　focus　on　manufacturing　technologies　for　alkaline　electrolysers,　high-pressure　cylinders,　and　diaphragm　compressors.　In　2024,　China　produced　36.5　million　tons　of　hydrogen,　of　which　77　%　was　grey　and　only　1　%　derived　from　electrolysis.　Storage　and　transportation　account　for　nearly　30　%　of　end-use　costs,　while　reliance　on　imported　compressors　increases　refuelling　station　expenses　by　approximately　40　%.　We　identify　key　bottlenecks,　including　limited　electrolyser　efficiency,　the　high　cost　of　carbon　fibres　for　Type　III/IV　cylinders,　and　insufficient　domestic　capacity　for　high-reliability　compressors.　To　address　these　challenges,　targeted　advances　are　proposed:　membrane　materials　with　engineered　hydrophilicity,　advanced　surface　modifications,　and　hydrophilic　inhibitors;　liner　design　incorporating　grooved-liner　braided　layers　with　double-fibre　configurations;　and　a　three-layer　diaphragm　compressor　architecture.　By　consolidating　fragmented　studies,　this　review　provides　the　integrated　manufacturing　perspective　on　China＇s　hydrogen　supply　chain,　offering　both　scientific　insights　and　practical　guidance　for　accelerating　cost-effective,　large-scale,　low-carbon　hydrogen　deployment.　©　2025　The　Authors
