{"product_id":"chpgdefc","title":"High Pressure (30 MPa) Gas-Diffusion Electrochemical Flow Cell, CHPGDEFC","description":"\u003cp\u003eA high-pressure gas-diffusion electrochemical flow cell is a high-performance reactor designed to operate at elevated pressures (typically 10–50 bar) to overcome the mass-transport limitations of gaseous reactants like CO2, N2, or O2. By combining the high surface area of a Gas Diffusion Electrode (GDE) with increased gas solubility from high pressure, these cells can achieve current densities (\u0026gt;500 mA\/cm2) that are nearly an order of magnitude higher than standard atmospheric flow cells.\u003c\/p\u003e\n\u003cp\u003eThe key advantages for the high-pressure operation are: (1)\u003cstrong\u003e Increased Solubility\u003c\/strong\u003e: According to Henry’s Law (C = k ' P), increasing the pressure of CO2 directly increases its concentration in the electrolyte layer near the catalyst. (2) \u003cstrong\u003eSuppressed Side Reactions\u003c\/strong\u003e: In CO2 reduction, higher pressure favors the formation of liquid fuels (like Formic Acid or Ethanol) and can suppress the unwanted Hydrogen Evolution Reaction (HER). (3) \u003cstrong\u003eReduced Bubble Size\u003c\/strong\u003e: High pressure keeps produced gas bubbles small, preventing them from \"masking\" the catalyst surface and increasing ohmic resistance.\u003c\/p\u003e\n\u003cp\u003eOperating a high-pressure flow cell requires more than just the cell itself, a sophisticated Back-Pressure Regulation (BPR) system is needed: (1) \u003cstrong\u003eDual BPRs\u003c\/strong\u003e: One for the gas outlet and one for the liquid outlet. They must be electronically synchronized to maintain a constant pressure drop across the fragile GDE. (2) \u003cstrong\u003eMass Flow Controllers (MFCs)\u003c\/strong\u003e: High-pressure rated MFCs to precisely deliver reactant gases. (3) \u003cstrong\u003eHigh-Pressure Pumps\u003c\/strong\u003e: Peristaltic pumps usually fail here; HPLC pumps or gear pumps are required to move electrolyte against the internal cell pressure.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eCHPGDEFC (C-HPGDEFC)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eCell body is made of Ti metal with good corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eFlow range: 0.01~50.00mL\/min, accuracy: ±1.0%\u003c\/li\u003e\n\u003cli\u003eMax. pressure: 30 MPa (0.1-20 mL\/min); 20 MPa (20-50 mL\/min)\u003c\/li\u003e\n\u003cli\u003ePressure accuracy: ±3% or 0.5MPa\u003c\/li\u003e\n\u003cli\u003eCell volume: 1 mL\u003c\/li\u003e\n\u003cli\u003eCell Dimension: 50mm×50mm\u003c\/li\u003e\n\u003cli\u003eInner Channel: 10×10 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePower Requirement\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V, 50\/60Hz, 200 W for flow pump.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eSingle Flow Pump for Controlling Anolyte\/Catholyte\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CHPGDEFC_main_160x160.png?v=1773160897\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003eDual Flow Pumps for Controlling Anolyte\/Catholyte\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e           \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CHPGDEFC_02_160x160.png?v=1773160896\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Weight\/Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003e12 kg\u003c\/li\u003e\n\u003cli\u003eL420mm * W300mm * H175mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003eThe cell components should be thoroughly cleaned and dried after use. \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e1. \u003ca href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/08957959.2026.2624012\"\u003eH.
