{"product_id":"cfcditc3e","title":"Flow Electrode Capacitive Deionization (FCDI) Test Cell (40mm*140mm) with Three Electrode Configuration, CFCDITC3E","description":"\u003cp\u003eIntegrating a three-electrode configuration into a Flow Electrode Capacitive Deionization (FCDI) test cell is a specialized setup used primarily for electrochemical research. While standard FCDI uses two electrodes to measure total cell voltage, a three-electrode setup allows you to isolate the half-cell potential of either the anode or the cathode. This is critical for understanding which electrode is limiting performance or if unwanted side reactions (like water splitting or carbon oxidation) are occurring at a specific interface.\u003c\/p\u003e\n\u003cp\u003eTo convert a standard FCDI cell into a three-electrode system, a Reference Electrode (RE) is supposed to be added into the electrolyte flow path without disrupting the electric field between the Working Electrode (WE) and Counter Electrode (CE). As for the reference electrodes, (1) \u003cstrong\u003eLuggin Capillary Method\u003c\/strong\u003e: A small capillary is inserted through the cell housing, positioned as close as possible to the surface of the Ion Exchange Membrane (IEM) on the side you wish to measure. (2) \u003cstrong\u003eIn-Line Placement\u003c\/strong\u003e: The RE (typically Ag\/AgCl or Hg\/Hg2SO4) is placed in a small chamber immediately downstream or upstream of the slurry flow, though this introduces \"iR drop\" (ohmic resistance) errors. (3) \u003cstrong\u003eIntegrated Micro-RE\u003c\/strong\u003e: Some advanced test cells use a wire-type reference electrode embedded directly into the flow channel spacer.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 528.45px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCFCDITC3E (C-FCDI-TC3E)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 126px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 126px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 126px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eFlow Plate: All-in-one graphite with serpentine channels\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eElectrode Gasket: PTFE\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMembrane Frame: Silicone for high quality planar sealing\u003c\/li\u003e\n\u003cli\u003eTubing Connection: Barbed hose fitting (tubing I.D. 2mm, O.D 4mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 54px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 54px;\"\u003e\u003cem\u003eCell Manifold Size \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 54px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eDefault effective area is 4 cm * 14 cm (64 cm2) \u003c\/li\u003e\n\u003cli\u003eOther types of active areas, such as (5 cm * 5 cm) are also available upon request.  \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCell size: W90×H180 mm \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 137.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 137.4px;\"\u003e\u003cem\u003eAssembling Diagram\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 137.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cp\u003e          \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CFCDITC3E_02_160x160.png?v=1774500742\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 136.25px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 136.25px;\"\u003e\u003cem\u003eFlow Pump (\u003cspan style=\"color: rgb(247, 8, 8);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 136.25px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe flow pump (Max. 300 mL\/min) can be supplied upon request   \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e         \u003cimg height=\"95\" width=\"117\" style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMEAFESFC_flow_pump_160x160.png?v=1772439579\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003eThe cell components should be thoroughly cleaned and dried after use.
