Membrane Electrode Assembly Electrolyzer Cells, Model: EC-MEA1

Description

Product Overview

The EC-MEA1 is a general-purpose bipolar-plate MEA electrolyzer cell for fundamental electrocatalysis research, including fuel cells, CO₂ reduction and water electrolysis. It also supports electrosynthesis and electrochemical wastewater-treatment studies. High-purity titanium plate construction, optional high-purity nickel plates, customizable flow fields, and standard heating and temperature-measurement ports provide a corrosion-resistant platform for constant-temperature laboratory testing.

Key Features

• Temperature-Controlled Electrochemical Testing: Standard heating and temperature-measurement ports support constant-temperature testing under defined electrochemical conditions.
• Corrosion-Resistant Plate Construction: High-purity titanium plates are standard, with high-purity nickel plates available for specialized electrochemical environments.
• Customizable Flow-Field Design: Supports serpentine, parallel, vein-pattern, comb-type and point-array flow fields for different reactant-distribution requirements.

Published Application Example

High-Rate CO₂ Electroreduction on Cu(100)-Rich Films in MEA Systems: Zhang et al. evaluated Cu(100)-rich electrodes for high-rate CO₂ electroreduction in a membrane electrode assembly electrolyzer. In a 4 cm² MEA configuration operated at 120 mA cm⁻², the system achieved an ethylene Faradaic efficiency of 55.8% and a full-cell electricity conversion efficiency of 40.2% toward C₂+ products, with stable operation for approximately 4.5 h. The system was further scaled to 25 cm² and operated at a total current of 12 A (480 mA cm⁻²), achieving a C₂+ single-pass yield of 13.2%.
