Advancing Electrochemical Research with High-Performance Electrolysis Cells

Versatile Electrolysis Cells for Modern Research

Electrolysis is a cornerstone technology for a sustainable future, driving hydrogen production, CO₂ reduction, and many other electrochemical conversions. Our laboratory-scale electrolysis cells are designed to give researchers the flexibility and reliability they need to advance the field — from catalyst screening through stack-level scale-up.

The Foundation of Innovation: Water Electrolysis

Water electrolysis separates water into hydrogen and oxygen — a cornerstone of green hydrogen research. Our cells support the three dominant water electrolysis chemistries (alkaline, AEM, and PEM) on the same hardware, with quick chemistry-to-chemistry swaps via gasket, membrane, and electrode changes.

Our cells support research across all three low-temperature water electrolysis routes:

• Alkaline Water Electrolysis (AWE): A mature technology using a liquid alkaline electrolyte. Our alkaline electrolyzer configuration supports a wide range of catalyst and membrane materials.
• Proton Exchange Membrane (PEM) Water Electrolysis: Runs on a solid polymer electrolyte and supports high current densities. Our PEM electrolyzer setup accepts standard and custom MEAs (membrane electrode assemblies) and GDLs (gas diffusion layers).
• Anion Exchange Membrane (AEM) Water Electrolysis: An emerging technology that combines the advantages of AWE and PEM and enables the use of non-precious-metal catalysts. Our AEM electrolyzer platform is built for catalyst and membrane development.

The same underlying X-Cell platform handles all three chemistries — just swap membranes, electrodes, and gaskets to reconfigure.

Modular by Design

Our cell design philosophy is centered on modularity. Whether you’re screening catalysts for the Oxygen Evolution Reaction (OER), developing novel anion exchange membranes, or building a multi-compartment electrolysis cell for CO₂ reduction or electrodialysis, our platforms can be configured to match your experiment. Electrodes, current collectors, bipolar plates, membranes, and flow fields are all interchangeable components.

Our Electrolysis Cell Platforms

The X-Cell — The Flexible Solution for R&D

The same underlying X-Cell platform supports alkaline, AEM, and PEM water electrolysis, CO₂ reduction, and electrodialysis. Active areas of 2.5 × 2.5 cm and 5 × 5 cm are interchangeable by gasket swap. Current collectors available in Ni, Ti, 316L stainless steel, Cu, Pt-coated Ti, Au-coated, and Ti; flat and interdigitated flow-field geometries available.

Multi-Compartment Cells for Advanced Chemistries

For experiments that need more than a standard two-compartment electrochemical cell, our X-Cell with 3 or 4 compartments enables middle-chamber chemistries — useful for CO₂ reduction, alkaline fuel cell research, and electrodialysis setups. A single platform converts between two-, three-, and four-compartment configurations by swapping gasket sets.

Reference Electrode Ports for Half-Cell Measurements

Our X-Cell with reference electrode ports adds four Luggin-capillary ports (two on-membrane, two at the electrode inlet) supporting up to three reference electrodes to the standard flow body. Unlike most commercially available cells, our reference electrode setup is usable at elevated temperature — up to 95 °C — enabling half-cell potential measurements under realistic operating conditions. This is particularly valuable for catalyst characterization, overpotential studies, and detailed kinetic analysis.

The M-Cell — 1 cm² Multipurpose Research Platform

Compact 1 cm² research cell with ten configurations covering closed, open, half-cell, and three-compartment modes. Ideal for catalyst screening, membrane evaluation, and proof-of-concept work where small material quantities and fast turnaround matter.

Scale-up Single-Cell Testing to Stack-Level Research

When your research moves beyond single cells, our electrolyzer stack platform (X-Stack) supports up to 9 cells in series for stack characterization, bipolar-plate screening, and scale-up studies. Two variants cover different electrode regimes:

• X-Stack with flat current collectors: Optimized for bipolar-plate material screening in alkaline-type electrolyzers and flow batteries. Requires electrodes thicker than ~1 mm.
• X-Stack with flow-field current collectors: Enables thin-electrode testing at stack level — down to very thin electrodes / <1 mm — making it suitable for AWE, AEM, PEM, and CO₂ electrolysis stack research.

Both variants support individual cell voltage measurement on the bipolar plates, so you can characterize each cell in the stack independently.

Why Choose Redox Flow Electrolysis Cells

• One platform covers AWE, AEM, PEM, CO₂RR, and ED via component swaps
• Standard 2.5 × 2.5 cm and 5 × 5 cm active areas interchangeable by gasket set

• Third-party membrane, electrode, and GDE compatible
• Rated to at least 90 °C for liquid-phase research
• Reference electrode integration for in-situ diagnostics
• Direct support from electrochemistry specialists.

Electrolysis Applications

While hydrogen production is the most prominent application, our electrolysis cells and research-grade electrolyzers are used across the electrochemical landscape: CO₂ electrolyzer setups for CO₂ reduction, desalination and ion removal, electrosynthesis, organic electrochemistry, and electrochemical metal recovery. The same X-Cell that runs PEM water electrolysis today can run a CO₂RR experiment tomorrow. Other supported chemistries include:

• Water electrolysis research (AWE, AEM, PEM)
• CO₂ reduction (CO₂RR)
• Electrodialysis and ion separation
• Organic electrochemistry and synthesis
• Electrocatalyst development
• Membrane characterization and benchmarking
• Gas-diffusion electrode (GDE) testing
• Desalination / ion removal

FAQ

What types of water electrolysis are these cells compatible with?

Our electrolysis cells support PEM, AEM, and alkaline water electrolysis on the same underlying platform. You change chemistry by swapping membranes, electrodes, and gaskets — no new hardware needed. The same cells also support CO₂ electrolysis, electrodialysis, flow battery research, and other electrochemical flow experiments.

What’s the difference between the X-Cell and the X-Stack?

The X-Cell is a single-cell platform for catalyst, membrane, and electrode research at the fundamental level. The X-Stack supports up to 9 cells in series, making it suitable for stack characterization, bipolar-plate screening, and scale-up studies. Most labs start with X-Cell for materials development and move to X-Stack when they’re ready to evaluate stack-level behavior.

Can I use my own membranes, electrodes, and gaskets?

Yes. The platform is built around interchangeable components, so you can integrate custom MEAs, custom GDLs, commercial membranes, or research-grade materials directly into the cell. Standard active-area options (2.5 × 2.5 cm and 5 × 5 cm) are designed to accept a wide range of third-party components.

Can I run half-cell measurements with a reference electrode?

Yes — the X-Cell with reference electrode ports adds four Luggin capillary ports that work up to 95 °C, which is higher than most commercial reference-electrode cells on the market. This enables realistic half-cell potential measurements under operating conditions rather than at room temperature only.

What’s the maximum operating temperature?

X-Cell variants are rated to app. 90 °C.

Which current collector and bipolar plate materials are available?

Standard options include Ni, Ti, stainless steel, Cu, Pt-coated Ti, and Au-coated Ti. Flat or interdigitated flow-field geometries are available depending on the cell variant.

Custom materials can be discussed for specific research needs.
