16 cm²/Cell Research-Grade Alkaline Water Electrolysis (AWE) Test Platform
Designed for the Development of Electrodes, Membranes, Catalysts, and Alkaline Water Electrolyzer Stacks
The Fueiceel® AWE16BC Series is a modular electrolyzer fixture platform specifically developed for alkaline water electrolysis (ALK/AWE) research and development. Featuring a standard 16 cm² active reaction area per Cell, it supports configurations ranging from a single-cell (1 Cell) to multi-cell stacks (20+ Cells). The platform is widely used for HER/OER catalyst evaluation, electrode development, membrane testing, electrolyzer structure optimization, stack development, and pilot-scale validation.
This product is positioned as a research electrolyzer fixture. It is supplied without membranes, electrodes, or catalyst materials, allowing users to freely configure different membrane, electrode, and catalyst systems according to specific experimental requirements. Compared with welded or permanently assembled electrolyzers, the AWE16BC is better suited for frequent assembly and disassembly, material replacement, and comparative studies, significantly improving R&D efficiency while reducing development costs.
A 30 wt% KOH (potassium hydroxide) solution is recommended as the circulating electrolyte. The fixture can be integrated with a circulation system, temperature control system, gas-liquid separation system, and DC power supply to form a complete ALK testing platform.

Under alkaline electrolyte conditions, the hydrogen evolution reaction (HER) occurs at the cathode, while the oxygen evolution reaction (OER) occurs at the anode.
Cathode (HER):
2H₂O + 2e⁻ → H₂ + 2OH⁻
Anode (OER):
4OH⁻ → O₂ + 2H₂O + 4e⁻
Overall Reaction:
2H₂O → 2H₂ + O₂
The membrane separates hydrogen and oxygen gases while allowing OH⁻ ions to migrate between the electrodes, maintaining charge balance within the cell.

Membrane → Anode Electrode → Nickel Foam Backer → Anode Flow Field Plate
Install the O-rings, fittings, and end plates, ensuring that each O-ring is fully seated in its sealing groove.
Tighten the bolts gradually in a diagonal (cross) sequence:
First Pass: 30% of the target torque
Second Pass: 60% of the target torque
Final Pass: 100% of the target torque
Avoid fully tightening one side at a time.
Perform gas-tightness and liquid-tightness tests using deionized water before filling the system with the KOH electrolyte. Confirm that there are no leaks before operation.
