GDE cells feed gas through a porous electrode while liquid electrolyte flows continuously across the front, creates a three-phase boundary of gas, liquid, and catalyst meeting inside the electrodes pores with a shorter transport path and reaches current densities a standard H-cell simply cannot.\u003c\/p\u003e\n\u003cp\u003eThis GDE flow cell can be used with a range of gas diffusion electrodes. The cell design has a more forgiving liquid gap than our advanced compact cell, as well as being easy to assemble and align. The continuously circulating liquid electrolyte chambers remove reaction products in real time and suppresses competing hydrogen evolution, while the S-shaped geometry delivers gas efficiently to a GDE over a 1 cm x 1 cm working area. This cell is well suited to method development, catalyst screening and applications such as:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbon dioxide reduction reaction (CO\u003csub\u003e2\u003c\/sub\u003eRR): \u003c\/strong\u003eThe catalytical conversion of carbon dioxide into value-added chemicals, syngas, or green fuels (like ethylene or formic acid)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNitrogen reduction reaction (NRR): \u003c\/strong\u003eNitrogen reduction reaction for nitrogen containing fertilizers production\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxygen reduction reaction (ORR): \u003c\/strong\u003eHydrogen peroxide electrosynthesis for water treatment and environmental remediation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"row display-flex\"\u003e\n\u003cdiv class=\"col-xs-12 col-sm-3 text-center margin-top\"\u003e\n\u003cimg loading=\"lazy\" width=\"50\" height=\"50\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/safe-enviroment-icon.svg\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003ePEEK Chambers \u0026amp;

A hydrophobic microporous layer, typically carbon black mixed with PTFE, stops electrolyte from flooding into the gas pores.
