Membrane Electrode Assembly (MEA) Electrolyzer Cell (Two-Electrode System, Graphite Bipolar Plate Type), Model: EC-MEA2

Membrane Electrode Assembly Electrolytic Cells EC-MEA2 A general-purpose MEA electrolytic cell with graphite flow fields for configurable reactant distribution and mass-transport research. Product Overview The EC-MEA2 is a general-purpose MEA electrolytic cell for CO₂ electroreduction, alkaline anion-exchange-membrane water electrolysis, fuel-cell evaluation and related electrochemical conversion studies. Internal high-purity isostatic graphite plates form the conductive reactant flow fields, while outer titanium fixture plates provide mechanical clamping. Multiple flow-field geometries and sizes support comparative mass-transport, water-management and catalyst-performance studies. Heating and temperature-measurement ports in the outer titanium plates enable controlled-temperature laboratory testing. Key Features High-Purity Graphite Flow-Field Plates High-purity isostatic graphite plates provide conductive flow channels for uniform reactant distribution in MEA-based electrochemical testing. Customizable Flow-Field Design Supports serpentine, parallel, vein-pattern, spiral, mesh and comb-type channels for mass-transport and water-management studies. Layered Graphite–Titanium Construction Internal graphite flow-field plates are enclosed by outer titanium fixture plates, providing stable mechanical clamping for repeatable MEA assembly.

Related Published Application Flow-Field Water Management in Zero-Gap CO₂ Electrolysis Xu et al. compared parallel, serpentine and lizard-inspired graphite cathode flow fields in a custom zero-gap CO₂ electrolyzer with a stainless-steel anode flow field. At 2.25 cm², the lizard-inspired design achieved a CO partial current density of 165.5 mA cm⁻² at 200 mA cm⁻² and maintained approximately 81.3% CO Faradaic efficiency for 24 h. Scale-up to 5.06 cm² was demonstrated at current densities up to 400 mA cm⁻². Capabilities Relevant to the EC-MEA2 Demonstrates MEA operation with configurable graphite cathode flow fields. Compares parallel, serpentine and customized channel geometries. Evaluates reactant transport, flooding and salt precipitation. Ongoing Application Studies Application studies using this model are currently underway. Note: The referenced study used a custom-made zero-gap CO₂ electrolyzer with graphite cathode flow-field plates and a configuration comparable to the EC-MEA2. It is included solely as a related application example; the article does not identify or use the EC-MEA2 model.
