{"product_id":"cehpfgdefeuef","title":"Gas Diffusion Electrode (GDE) Flow Electrolyzer with Ultrathin Electrode Frame (~1mm) for Electrosynthesis of Hydrogen Peroxide and Formate, CEHPFGDEFEUEF","description":"\u003cp\u003eIn a GDE (Gas Diffusion Electrode) flow electrolyzer, the \"ultrathin electrode frame\" is a critical architectural desgin to manage the gas-liquid biphase reaction, where gaseous reactants (like CO2) must meet liquid electrolytes and solid catalysts at a perfectly balanced triple-phase boundary.\u003c\/p\u003e\n\u003cp\u003eTraditional flow cell frames are often bulky (several millimeters thick), which increases the distance between electrodes and adds ohmic resistance. The shift to ultrathin frames (typically 0.5–1.2 mm) provides several key benefits: (1) \u003cstrong\u003eZero-Gap Proximity\u003c\/strong\u003e: It minimizes the \"gap\" in the electrolyte chamber, allowing the system to operate at industrial current densities (\u0026gt;500 mA\/cm2) with lower voltage penalties. (2) \u003cstrong\u003eStray Current Mitigation\u003c\/strong\u003e: Modern frames use high-performance polymers like PEEK or PPS with integrated feed\/discharge channels designed to reduce stray currents that can lead to power loss and hardware deterioration. (3) \u003cstrong\u003ePrecision Compression\u003c\/strong\u003e: The thinness allows for more uniform mechanical pressure across the GDE, ensuring that the fragile porous layers aren't crushed while maintaining airtight seals for the gas phase.\u003c\/p\u003e\n\u003cp\u003eThe O2-to-H2O2 reaction is highly dependent on mass transport, making the \"Flow-By\" GDE configuration essential. \u003cstrong\u003eGas Phase\u003c\/strong\u003e: Pure O2 or filtered air is fed to the back of the GDE. This solves the problem of oxygen's low solubility in water, allowing for current densities of 200–800 mA\/cm2. \u003cstrong\u003eLiquid Phase\u003c\/strong\u003e: A dilute electrolyte (often 0.1 M Na2SO4 or seawater) flows past the catalyst-coated side of the GDE. High flow rates are used to \"sweep\" the H2O2 away as soon as it forms to prevent it from being further reduced to water.\u003c\/p\u003e\n\u003cp\u003eThe three compartment design with two membranes can be used to catholyte, anolyte, and gas chambers, which allows the direct production of liquid formic acid (HCOOH) without salt contamination.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%;
