Description
Product Overview
The EC-MEA5 is a modular MEA electrolyzer designed for studies in which flow-channel thickness and flow-field configuration are controlled experimental variables. Its interchangeable flow-channel structure enables comparative investigation of mass transport, flow behavior, and electrochemical response within a consistent cell architecture. High-purity PTFE flow-field components and titanium clamping plates provide chemically resistant and mechanically stable construction, supporting CO₂ electroreduction, water electrolysis, and broader MEA configuration studies.
Key Features
- Interchangeable PTFE Flow Channels: Replaceable PTFE flow-channel inserts allow channel thickness to be varied according to experimental requirements.
- Chemical-Resistant Construction: High-purity PTFE flow-field components provide chemical resistance, while titanium clamping plates provide stable mechanical support.
- Multiple Flow-Field Sizes: Multiple flow-field sizes are available for different MEA active areas and research-scale electrolysis requirements.

Related Published Application
CO₂ Electrolysis in a Modular MEA Cell with Interchangeable Flowplates: Moss et al. developed an X-ray-compatible MEA electrolyzer for operando CO₂ electrolysis studies. Its flow-field assembly was designed for easy flowplate exchange, allowing different materials and channel geometries to be evaluated within the same cell architecture. Using a sputtered Cu gas-diffusion cathode, the study evaluated gaseous-product Faradaic efficiencies and cell voltage at 150, 200, and 250 mA cm⁻². The study illustrates how exchangeable flow-field components can support comparative MEA research under controlled operating conditions.

Capabilities Relevant to the EC-MEA5
- Illustrates the use of exchangeable flow-field components in MEA research.
- Shows how flow-field changes can be compared within a common cell architecture.
- Provides a relevant reference for flow-field and mass-transport studies.
Note: The cited publication used a custom-built X-ray-compatible MEA electrolyzer, not the EC-MEA5. Its interchangeable-flowplate concept is structurally comparable to the replaceable flow-channel design of the EC-MEA5 and is included solely as a related application example.
