{"product_id":"cerfbtc","title":"Economic Redox Flow Battery Testing Cell without Flow Channels, CERFBTC","description":"\u003cp\u003eA Redox Flow Battery (RFB) testing cell is the core electrochemical component of a flow battery system where the conversion between electrical and chemical energy occurs. Unlike traditional batteries, the energy is stored in liquid electrolytes (anolyte and catholyte) which are pumped through this cell during operation.\u003c\/p\u003e\n\u003cp\u003eA standard lab-scale RFB cell is usually a \"sandwich\" stack held together by end-plates.\u003c\/p\u003e\n\u003cp\u003e(1) \u003cstrong\u003eEnd Plates\u003c\/strong\u003e: Usually made of heavy-duty stainless steel or aluminum. They provide the mechanical pressure required to seal the cell and ensure low contact resistance.\u003c\/p\u003e\n\u003cp\u003e(2) \u003cstrong\u003eCurrent Collectors\u003c\/strong\u003e: Often gold-plated or high-purity copper plates that transfer electrons from the internal electrodes to the external circuit.\u003c\/p\u003e\n\u003cp\u003e(3) \u003cstrong\u003eBipolar Plates (Flow Fields\u003c\/strong\u003e): Typically made of high-density graphite or graphite-polymer composites. These plates have machined channels (e.g., serpentine, parallel, or interdigitated) to distribute the liquid electrolyte evenly across the electrode surface.\u003c\/p\u003e\n\u003cp\u003e(4) \u003cstrong\u003ePorous\u003c\/strong\u003e \u003cstrong\u003eElectrodes\u003c\/strong\u003e: Usually carbon felt or graphite felt.
