{"product_id":"crfbtcssfc","title":"Redox Flow Battery Testing Cell Stack with Serpentine Flow Channels, CRFBTCSSFC","description":"\u003cp\u003eA Redox Flow Battery (RFB) testing stack is a laboratory-scale or pilot-scale assembly used to evaluate the electrochemical performance, fluid dynamics, and durability of a battery design before full-scale commercialization. While a \"single cell\" tests a specific material (like a new membrane), a stack tests how multiple cells interact when connected electrically in series and fluidically in parallel.\u003c\/p\u003e\n\u003cp\u003eA testing cell stack is a \"sandwich\" of multiple repeating units. The primary components are: (1) \u003cstrong\u003eBipolar Plates (BPP)\u003c\/strong\u003e: These plates separate individual cells. They must be electronically conductive to transfer electrons between cells but chemically inert to the electrolyte. They often feature flow fields (serpentine or interdigitated patterns) to distribute the liquid evenly. (2) \u003cstrong\u003ePorous Electrodes\u003c\/strong\u003e: Usually made of carbon felt or carbon paper, these provide the high surface area needed for the redox reactions to occur. (3) \u003cstrong\u003eIon-Exchange Membrane (IEM)\u003c\/strong\u003e: Positioned between the positive and negative half-cells of each unit to allow charge-balancing ions to pass while preventing the \"crossover\" of the active redox chemicals. (4) \u003cstrong\u003eEnd Plates \u0026amp; Current Collectors\u003c\/strong\u003e: Heavy-duty outer plates (often stainless steel or high-strength plastic) that provide the clamping force to seal the stack. Copper current collectors are placed just inside the end plates to connect the stack to the power supply.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 1194px;\" 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\u003cp\u003e\u003cspan\u003eCRFBTCSSFC (C-RFB-TCSSFC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 184.8px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 184.8px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 184.8px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEnd Plates: PEEK material\u003c\/li\u003e\n\u003cli\u003eCurrent Collector: Graphite plate with serpentine flow channels\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\u003c\/li\u003e\n\u003cli\u003eTubing Connection: Barbed hose fitting \u003c\/li\u003e\n\u003cli\u003eMax.
