Gas Diffusion Electrochemical Cell (Three-Electrode System), Model: EC-GDE2

EC-GDE2 Gas Diffusion Electrochemical Cell A cost-effective, three-chamber GDE flow cell for rapid feasibility validation and catalyst screening. Product Overview The EC-GDE2 is a cost-effective gas diffusion electrochemical flow cell designed for rapid feasibility validation and electrocatalyst screening. Its three-chamber, three-electrode architecture supports direct reactant-gas delivery to a sheet-type gas diffusion electrode and controlled electrolyte circulation, providing a flexible laboratory platform for gas-fed electrochemical research. Key Features Cost-Effective Flow-Cell Platform Supports rapid feasibility validation and routine gas-diffusion electrode screening. Controlled Three-Chamber Operation Separates gas, catholyte, and anolyte pathways for controlled three-electrode testing. Flexible Cell-Body Options PMMA, PTFE and PEEK configurations support selection for different experimental requirements. Typical Applications Gas-Diffusion Electrode Studies Evaluating sheet-type GDEs under controlled electrolyte-flow conditions. CO₂ Electroreduction Research Investigating catalytic activity and selectivity toward C₁ and C₂+ products. Electrocatalyst Screening Comparing catalyst structures, electrochemical activity and current-density response.

Published Application Example High-Rate CO₂ Electroreduction to Multicarbon Products A three-chamber flow cell was used to evaluate Cu(100)-rich gas-diffusion electrodes for CO₂ electroreduction to ethylene and C₂+ products. Direct CO₂ delivery to the catalyst layer, continuous 2 M KOH circulation and three-electrode control enabled investigation of catalyst-facet effects, current-density response, product selectivity and short-term stability. The study demonstrates the role of this cell architecture in rapid laboratory-scale CO₂RR validation. Demonstrated EC-GDE2 Capabilities Supports direct reactant-gas delivery to sheet-type GDEs under continuous electrolyte-flow conditions. Enables controlled three-electrode evaluation of catalyst activity, product selectivity and current-density response. Suitable for rapid feasibility testing and short-term stability studies in CO₂ electroreduction. Additional Published Applications Lin, Y. et al. Nat. Commun. 2023, 14, 3575.
