Its sandwich architecture can be reconfigured for gas-diffusion, solid-electrolyte, membrane-electrode-assembly and metal-air operation. A compact 1.2 mm anode-cathode gap shortens the ionic transport path, supporting reduced cell resistance, controlled mass transport and moderate-to-high-current-density testing. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFour-Mode Modular Architecture\u003c\/strong\u003e\u003cbr\u003eInterchangeable sandwich components support four configurable operating modes within a single platform, enabling rapid reconfiguration for diverse electrochemical studies while reducing the need for multiple dedicated reactors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompact 1.2 mm Electrode Gap\u003c\/strong\u003e\u003cbr\u003eThe shortened ionic transport path helps reduce ohmic loss and supports controlled moderate-to-high-current-density testing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRobust Titanium-PEEK Construction\u003c\/strong\u003e\u003cbr\u003eHigh-purity titanium and chemically resistant PEEK provide durable construction for repeated assembly and operation across different electrolyte environments. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eGas-Fed Electrocatalysis\u003c\/strong\u003e\u003cbr\u003eEvaluating gas-diffusion electrodes for CO₂ reduction and other gas-involved electrochemical reactions at moderate-to-high current densities.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMultimode Electrochemical Reactor Studies\u003c\/strong\u003e\u003cbr\u003eInvestigating catalyst performance, mass transport, product collection and operational stability across configurable reactor architectures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMetal–Air Battery Research\u003c\/strong\u003e\u003cbr\u003eSupporting zinc–air and lithium–air studies, including electrode activity, charge–discharge performance and cycling stability.\u003cbr\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
