{"product_id":"csfgpecfcgde","title":"Photoelectrochemical (PEC) Flow Cell with Gas-Diffusion Electrode (GDE) for Solar Fuel Generation, CSFGPECFCGDE","description":"\u003cp\u003eA Photoelectrochemical (PEC) Flow Cell with a Gas-Diffusion Electrode (GDE) is an advanced reactor design that overcomes the primary limitation of traditional solar fuel systems: the low solubility and slow diffusion of gases (like CO2 or N2) in liquid electrolytes. By integrating a GDE—a porous, hydrophobic electrode—directly into a PEC flow cell, gaseous reactants can reach the photoactive catalyst surface at much higher rates, enabling \"solar-to-fuel\" (STF) conversion at commercially relevant current densities.\u003c\/p\u003e\n\u003cp\u003eThe design typically consists of a \"three-phase interface\" where the solid catalyst, liquid electrolyte, and gaseous reactant meet. (1) \u003cstrong\u003eOptical Window\u003c\/strong\u003e: Usually made of Quartz, allowing solar or simulated light to reach the photoelectrode without significant absorption losses. (2) \u003cstrong\u003eGas-Diffusion Photoelectrode\u003c\/strong\u003e: A porous substrate (like carbon paper or PTFE-treated carbon cloth) coated with a semiconductor (e.g., TiO2, Cu2O, or BiVO4). The gas is fed from the \"dry\" back-side, while the \"wet\" front-side is in contact with the electrolyte. (3) \u003cstrong\u003eFlow Channels\u003c\/strong\u003e: Serpentine or parallel channels that circulate the liquid electrolyte to remove products and manage local pH levels.\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\u003cul\u003e\n\u003cli\u003eCSFGPECFCGDE (C-SFG-PECFCGDE)\u003c\/li\u003e\n\u003c\/ul\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\u003eThe whole photoelectrochemical cell was constructed with a photoelectrode flow chamber with optical window, gas chamber, and a counter flow chamber.\u003c\/li\u003e\n\u003cli\u003eA gas-diffusion-type photoelectrode can be tested for CO2\/N2 reduction, which addresses the light blocking issue of photoelectrode in a regular PEC system.
