Gas Diffusion Electrochemical Cell (Entry-Level), Model: EC-GDE1

Description

Product Overview

The EC-GDE1 is an entry-level gas diffusion electrochemical cell designed for introductory electrochemical experiments. It features a PEEK three-chamber body and a three-electrode configuration. Quick-opening lids simplify assembly and access, while gas inlet and outlet ports on both electrode sides and dedicated sampling ports support flexible experimental configurations.

Related Published Application

Static Gas-Fed CO Electroreduction to Formate: A commercial static, gas-fed, three-electrode cell was used to evaluate SnO-coated gas diffusion electrodes for CO electroreduction to formate. Using a static electrolyte and controlled CO supply, the setup enabled systematic investigation of catalyst loading, current-density response and early-stage electrode stability. This comparable cell architecture illustrates the intended role of the EC-GDE1 in laboratory-scale GDE screening and gas-fed electrochemical studies.
