Safety note:
The use of a High-Pressure Electrochemical Cell involves working with equipment capable of withstanding elevated pressures and conducting experiments with potentially reactive chemicals. Ensuring safety during operation is paramount to prevent accidents and protect personnel and equipment. Below are key safety considerations to observe when using the High-Pressure Electrochemical Cell:
1. Prior to operation, all personnel involved should receive comprehensive training on the setup, operation, and safety protocols associated with the High-Pressure Electrochemical Cell. Only trained individuals familiar with the equipment should be permitted to operate it.
2. Adhere strictly to the specified pressure limitations of the High-Pressure Electrochemical Cell. Do not exceed the recommended pressure range to prevent over-pressurization, which could lead to equipment failure and potential hazards.
3. Ensure that all materials, including electrodes, seals, and electrolytes, are compatible with the pressure and chemical environment inside the cell. Incompatibilities could result in leaks, corrosion, or other safety hazards.
4. Verify that the pressure relief mechanism is in place and functioning correctly. This mechanism is crucial for safely releasing excess pressure in the event of over-pressurization.
5. Regularly inspect the seals and connections of the High-Pressure Electrochemical Cell for signs of wear, damage, or leaks. Replace any compromised components promptly to maintain sealing integrity and prevent pressure-related accidents.
6. Establish clear emergency procedures, including evacuation routes and protocols for handling pressure-related incidents. Ensure that all personnel are aware of these procedures and know how to respond effectively in case of emergencies.
7. Wear appropriate Personal Protective Equipment (PPE), including safety glasses, gloves, and lab coats, when operating the High Pressure Electrochemical Cell. Additional PPE may be necessary depending on the specific experimental conditions and hazards involved.
8. Supervise experiments closely and monitor the High-Pressure Electrochemical Cell continuously during operation. Respond promptly to any abnormalities or unexpected changes in pressure or performance.
By adhering to these safety guidelines and exercising caution and diligence, users can minimize risks and ensure the safe and effective operation of the High-Pressure Electrochemical Cell in the laboratory. Always prioritize safety to protect yourself, your colleagues, and the integrity of the experimental setup.

NREL High-Pressure Low-Temperature Electrolysis Cell (redox.me)
Read moreDeveloped by National Renewable Energy Laboratory (NREL) High-Pressure Low-Temperature Electrolysis (LTE) Cell is on open-source cell hardware designed for repeated reassembly. This work was planned and funded by the U.S. Department of Energy’s H2NEW consortium.
Redox.me offers a 25 cm² PEM variant produced based on the technical documentation from NREL, as well as other variants developed by redox.me according to NREL guidelines. In the former, the flow field pattern is directly translated from 25 cm² PEM variant. The dissemination of these products aims to facilitate easy access to this equipment for a wide range of users. However, if you have the capability to produce the 25 cm² PEM variant on your own, we encourage you to use the open-source files. It may turn out that if you have access to your own technical resources, this will be a more cost-effective option. 3D CAD models and 2D technical drawings for variant 25 cm² PEM are available for download.
High pressure LTE operation can reduce operating costs, as it is more efficient to produce electrochemically pressurized hydrogen compared to using downstream mechanical compressors. However, the cell is also compatible with ambient pressure LTE.
The cell can accommodate porous transport layers of varying thicknesses. To achieve this, the number of gaskets on each side of the cell can be increased, providing a larger volume for the porous transport layer.
One benefit of the smaller surface area variants (1 cm² and 4 cm²) is their compatibility for testing with a potentiostat and booster. In these cases, the current levels are typically within the acceptable range for most boosters. However, for larger active surfaces with current densities up to 6 A/cm², a high-power programmable DC power supply may be required.Application note:
The documents and drawings linked below outline the design of low-temperature electrolysis hardware that is intended to meet leak testing standards as per ASME B31.1. They also provide comprehensive cell assembly instructions and a procedure for performance benchmarking. The responsibility for safe operation at both ambient and elevated pressures lies solely with the end user, and each individual cell should be assessed on a case-by-case basis. The sealing effectiveness may be influenced by factors such as machining quality, components used in cell assembly, operating conditions, and the operational history. Pressure operations should only be conducted on qualified test stands by trained operators.Specification:

Sample Holder 25 mm x 25 mm (redox.me)
Read moreThe sample holder (known also as flat specimen holder) is used for holding flat, circular or square/rectangular samples. It enables contacting the sample from the front (e.g. ITO/FTO glass, Monolayer Graphene on SiC, or Boron-Doped Diamond thin film on various substrates) and from the back (e.g. metal specimen, Glassy Carbon plate, Boron-Doped Diamond plate). The default nominal aperture is 1cm2, but other value can be provided on request. The large electrical contact with Tantalum (formerly Copper) foil surface (not being in contact with an electrolyte) ensures optimal current collection by minimizing electrical resistance and unifying current distribution. The rod with electrical connection has a diameter of 6 mm, which makes the sample holder compatible with our voltammetry cells and jacketed cells, as long as it fits in. We may also provide an adapter to install this sample holder in openings larger than 6 mm dia.
The sample holder elements are constructed with materials that are inert to the electrochemical system (PEEK, Fluorocarbons). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is well sealed which prevents the electrolyte to leak inside.
Application note
The sample holder is used largely for corrosion studies. It can be installed in a beaker type cell as well as in testing environments such as open water reservoirs, cans, tanks etc. It can also be used wherever it is necessary to make an electrode using a thin layer of an active material deposited on a flat substrate (conducting or insulating).Specification

Working Disk Electrode – PEEK body 6 mm dia., 70 mm long (redox.me)
Read moreThis is a Standard Working Electrode in which a disk of electrode material (glassy carbon, gold, platinum, silver, boron-doped diamond, palladium, titanium, and copper) is embedded into the PEEK body by a compressed PTFE or PEEK sleeve. It well fits aqueous and organic solvent electrolyte requirements. If you need a different disk material, please contact us.
Application note
The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol or isopropanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-ring (all included in the package). Instruction on maintenance is provided on the Electrode Polishing Kit product page.Specification
