Our electrolysis product line supports cutting-edge research in water splitting, hydrogen production, catalyst testing, and emerging electrolysis technologies. Our electrochemical flow cells and components are designed to be flexible and modular — engineered for electrolyzer R&D that lets you test new membranes, electrodes, catalyst materials, or electrolyte solutions. Our setups are compatible with alkaline, AEM, PEM, and CO₂ electrolysis systems, as well as desalination and electrodialysis, and are scalable from catalyst screening at the 1 cm² level to system-level validation with multi-cell stacks.
Whether you’re screening catalysts for alkaline water electrolysis, testing membranes for AEM or PEM systems, or exploring CO₂ reduction and electrodialysis, our platform gives you a single hardware ecosystem that adapts to your chemistry — not the other way around.
Our flow-cell systems and components integrate into a wide range of electrolysis setups:
Our research electrolysis cells and components are organized into two main groups: core flow cells and supporting accessories.
Our electrolysis components are used globally by researchers and engineers working on:
We support custom designs and are happy to assist with project-specific requirements, including:
Our team is here to help you accelerate your electrolysis research — whether you’re building a proof of concept or optimizing for scale-up.
Our electrolysis cells and components are designed for PEM, AEM, and alkaline water electrolysis (AWE), as well as CO₂ electrolysis (CO₂RR), electrodialysis, capacitive deionization (CDI), and other liquid-phase electrochemical processes. The same underlying X-Cell platform can be reconfigured for different chemistries by swapping membranes, electrodes, and gaskets.
Three cell platforms, each optimised for a different research phase. The M-Cell (1 cm²) is a multipurpose Full Cell and Half Cell for catalyst screening, half-cell electrolyser testing, cyclic voltammetry, and kinetic studies — its small active area keeps material consumption low, and its ten operating configurations cover closed cell, open cell, half-cell, and three-compartment modes. The X-Cell (2.5 × 2.5 cm and 5 × 5 cm) is the workhorse single-cell platform for membrane, electrode, and catalyst performance characterisation at realistic current densities. The X-Stacks support up to 9 cells in series, designed for stack-level characterisation, bipolar-plate screening, and upscaling studies. Most labs start with M-Cell for fundamental and catalyst-development work, move to X-Cell for performance characterisation, and bring in an X-Stack when evaluating stack-level behaviour.
Yes. The platforms are built around interchangeable components, so you can integrate custom MEAs, commercial or research-grade membranes, custom-formulated catalyst layers, and third-party GDEs. Standard active-area sizes (1 cm² on M-Cell, 2.5 × 2.5 cm and 5 × 5 cm on X-Cell and X-Stack) are designed to accept a wide range of materials.
A functional electrolyzer R&D setup typically includes a flow cell, electrolyte reservoirs, a pump, temperature control, gas separation (for water-splitting experiments), and hydraulic connections. We offer all of these as individual components or as pre-configured packages. If you’re unsure which accessories you need, we can help scope a complete setup for your application.
Yes. Beyond our standard catalog, we routinely collaborate with researchers on custom active-area sizes, non-standard materials, novel flow-field geometries, and specialized multi-compartment architectures. For joint development with academic or industrial partners, contact us to discuss project scope.
M-Cell and X-Cell variants are rated to at least 90 °C.
Our accessories use standard fittings (Swagelok 1/8″ or 1/4″ depending on model) and inert wetted surfaces, so they integrate easily with existing lab equipment. Our temperature control units in particular are designed as chemistry-agnostic inline heat exchangers that work with flow cells from any manufacturer.
