{"product_id":"czgfctsih","title":"Zero-Gap Flow Cell Testing System with Integrated Heating for Redox Flow Battery, Electrolyzer, and Fuel Cell, CZGFCTSIH","description":"\u003cp\u003eA Zero-Gap Flow Cell Testing System with Integrated Heating is a high-performance, versatile laboratory fixture engineered to evaluate electrochemical energy conversion and storage devices—including Redox Flow Batteries (RFBs), Water Electrolyzers (PEM\/AEM), and Fuel Cells (PEMFC\/AEMFC). By eliminating the inter-electrode gap and pressing the flow fields directly against the Membrane Electrode Assembly (MEA) or ion-exchange membrane with compressed carbon\/metal felts, zero-gap architecture drastically minimizes ohmic resistance and mass transport polarization.\u003c\/p\u003e\n\u003cp\u003eA robust zero-gap test cell fixture typically features a modular sandwich construction designed to withstand uniform compression, high temperatures, and aggressive chemical environments. (1) \u003cstrong\u003eEnd Plates\u003c\/strong\u003e: Manufactured from corrosion-resistant metals (such as 316L stainless steel or titanium) or rigid insulating engineering plastics (PVDF, PEEK) to provide uniform mechanical clamping force and structural rigidity. (2) \u003cstrong\u003eCurrent Collectors\u003c\/strong\u003e: Gold-plated copper, nickel, or titanium foil\/plates positioned between the flow field and end plate to ensure low-resistance electronic contact. (3) \u003cstrong\u003eFlow Field Plates\u003c\/strong\u003e: (i) For RFBs: Graphite or polymer-carbon composite plates featuring serpentine, parallel, or interdigitated channels to distribute liquid electrolytes evenly through porous carbon felt electrodes. (ii) For Electrolyzers \u0026amp; Fuel Cells: Titanium (anode\/cathode) or graphite blocks with fine, laser-machined or etched flow channels optimized for gas-liquid two-phase flow. (4) Gaskets \u0026amp; Sealing: High-performance elastomers (PTFE, Viton, EPDM, or Kalrez) selected for chemical inertness against concentrated acids, alkaline solutions, or organic solvents across broad temperature ranges.\u003c\/p\u003e\n\u003cp\u003eControlling and maintaining precise thermal profiles is critical for studying activation kinetics, exchange current densities, and ionic conductivity under realistic operating conditions. (1) \u003cstrong\u003eEmbedded Cartridge Heaters\u003c\/strong\u003e: High-wattage stainless-steel cartridge heaters inserted directly into the perimeter of the metallic end plates, providing uniform conductive heat transfer into the active core. (2) \u003cstrong\u003eFluid-Circulating Jackets\u003c\/strong\u003e: Alternatively, internal or external liquid heating channels coupled with a recirculating thermal bath can be utilized for precise, isothermal long-term testing. (3) \u003cstrong\u003eSensor Placement \u0026amp; PID Control\u003c\/strong\u003e: K-type or PT100 thermocouples embedded within close proximity to the active window (rather than just the outer edge of the end plate) linked to a dedicated PID temperature controller to eliminate thermal overshoot and maintain stability (~ 0.5 °C) from ambient up to 90 °C–120 °C (or higher for specialized high-temperature systems. (4) \u003cstrong\u003eThermal Insulation\u003c\/strong\u003e: PEEK or Teflon thermal break plates positioned between the heated test fixture and the hydraulic\/mechanical clamping frame to prevent heat loss to the ambient environment.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 1435.86px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 53.2125px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 53.2125px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 53.2125px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCZGFCTSIH (C-ZGFCTS-IH)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 291.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 291.2px;\"\u003e\u003cem\u003eCell Structure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 291.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEnd Plates: Stainless Steel Plate\u003c\/li\u003e\n\u003cli\u003eManifold: Graphite plate with flow channels\u003c\/li\u003e\n\u003cli\u003eCurrent Collector: Gold-coated copper\u003c\/li\u003e\n\u003cli\u003eElectrode: Graphite felt (T=3 mm)\u003c\/li\u003e\n\u003cli\u003eElectrode Gasket: PTFE\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMembrane Frame: Silicone (chemical resistance)\u003c\/li\u003e\n\u003cli\u003eTubing Connection: Barbed hose fitting \u003c\/li\u003e\n\u003cli\u003eMax.
