Channel independence matters whenever the anode and cathode reactions have very different requirements. For instance, asymmetric bipolar-membrane operation, or pairing a demanding cathodic reaction with an anode that needs an entirely different electrolyte to run efficiently.  An all-PEEK construction handles running each compartment at its own extreme without the pitting, corrosion, or metal-ion leaching that Ti or Ni bodies can suffer under acidic, alkaline, or halide-containing electrolytes.\u003c\/p\u003e\n\u003cp\u003eAs with our other flow cells, the cathode is a gas diffusion electrode consistng of: a porous conductive support, a PTFE-based hydrophobic microporous layer, and a catalyst layer, forming the three-phase boundary where gas, electrolyte, and catalyst meet. In this full-cell configuration, that boundary sits on the catholyte side of the membrane, while the anode runs independently in its own compartment. Reactant gas is supplied directly to the catalyst layer, bypassing solubility bottlenecks and preventing mass-transport limitations.\u003c\/p\u003e\n\u003cdiv class=\"row display-flex\"\u003e\n\u003cdiv class=\"col-xs-6 col-sm-4 col-md-3 text-center margin-top\"\u003e\n\u003cimg loading=\"lazy\" width=\"50\" height=\"50\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/large-tick-icon.svg\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eAll-PEEK Body\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eChemically inert across\u003cbr\u003ea broad pH range\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-6 col-sm-4 col-md-3 margin-top text-center\"\u003e\n\u003cimg loading=\"lazy\" width=\"50\" height=\"50\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/separate-electrodes-icon.svg\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eThree-phase Boundary Design\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003ePreventing mass-transport\u003cbr\u003elimitations\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-6 col-sm-4 col-md-3 text-center margin-top\"\u003e\n\u003cimg alt=\"Versatile electronic applications\" height=\"50\" loading=\"lazy\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/flow-icon.svg\" width=\"50\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eDual Flow Chambers\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eIndependent anolyte \u0026amp;\u003cbr\u003ecatholyte control\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-6 col-sm-4 col-md-3 text-center margin-top\"\u003e\n\u003cimg loading=\"lazy\" width=\"50\" height=\"50\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/customer-support-icon.svg\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eExpert Support\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eFrom in-house scientists \u0026amp;
