Unlike felt, which is open and airy, foil is made by compressing expanded graphite flakes into a solid sheet without binders. This is why the graphite foil as the layer behind the felt to prevent the liquid from touching your metal end-plates and to ensure a good electrical path. \u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 175.562px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 51.3625px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 51.3625px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 51.3625px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCFBEFCGF (C-FBEFC-GF)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 53px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 53px;\"\u003e\u003cem\u003eSheet Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 53px;\"\u003e\n\u003cp\u003e(2) Sheet: T 0.05mm * W 200mm * L 250mm\u003c\/p\u003e\n\u003cp\u003e(3) Roll: T 0.1mm * W 500mm * L 2m\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003eOther sheet dimensions can also be supplied upon request. \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 35.6px;\"\u003e\u003cem\u003eTensile Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 35.6px;\"\u003e\n\u003cp\u003e≥4.5 MPa\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 35.6px;\"\u003e\u003cem\u003eTemperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 35.6px;\"\u003e\n\u003cp\u003e-200 to 700 °C\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"SXHF","offers":[{"title":"Sheet: T 0.05mm * W 200mm * L 250mm   5 pcs\/pack","offer_id":47240218968294,"sku":"CFBEFCGFST005","price":29.0,"currency_code":"USD","in_stock":true},{"title":"Roll: T 0.1mm * W 500mm * L 2m","offer_id":47240219001062,"sku":"CFBEFCGFRT01","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CFBEFCGF.png?v=1767299943"},{"product_id":"cfbefccfos","title":"Carbon Foam Sheet for Flow Battery, Electrolyzer, and Fuel Cell, CFBEFCCFOS","description":"\u003cp\u003eCarbon foam is a rigid, 3D skeletal structure with an open-cell architecture (97% void volume). \u003c\/p\u003e\n\u003cp\u003e(1) In \u003cstrong\u003eRedox Flow Batteries (RFB)\u003c\/strong\u003e, carbon foam acts as a high-surface-area 3D electrode or current collector. Unlike felt, carbon foam does not compress or \"slump\" over time. This maintains consistent flow channels and prevents the \"channeling\" effect where electrolyte misses parts of the electrode.
