Description
Product Overview
The EC-MEA3R is a visualization membrane electrode assembly (MEA) electrolyzer designed for CO₂ electroreduction, water electrolysis, and related electrochemical studies. Round quartz windows on both the cathode and anode sides provide optical access for direct observation and high-speed imaging during operation. An open-view serpentine cathode flow field and multi-channel parallel anode flow field expose key gas–liquid transport regions, while high-purity titanium plates provide corrosion resistance and stable MEA clamping.
Key Features
- Dual-Sided Optical Access: Round quartz windows on both electrode sides enable direct observation and high-speed imaging of operating MEAs.
- Open-View Flow Fields: An open-view serpentine cathode flow field and multi-channel parallel anode flow field expose key gas–liquid transport regions.
- High-Purity Titanium Construction: High-purity titanium plates provide corrosion resistance and stable mechanical clamping for repeatable MEA assembly.
