  Standard electrochemical cell setup (redox.me)

  This is a stationary solution standard electrochemical (electrolytic) cell for measurements of electrodes in a form of:

  a) rod/disc (6 mm dia.),

  b) thin film deposited on a flat substrate (using a sample holder) and

  c) free-standing membrane (using the basic sample holder).

   

  The working, counter, and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The cell has two spare ports for connection of e.g. thermometer, Clark electrode, pH meter electrode, or other 6 mm dia. electrode/probe. 

  The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte. The jacketed model is available here. 

   

  Application note
  The reference electrode tip should be placed close to a working electrode center. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.

   

  Specification:
  maximum electrolyte volume: 100, 150, 200, 250, 350, 500 or 1000 mL
  electrode plug diameter: 6 mm

  Platinum Coated Titanium Mesh Electrode with Holder – set of 10 pcs (redox.me)

  The metal counter (auxiliary) electrode is provided in electrochemical cell as a current sink to shunt excess current away from the reference electrode. Platinum Coated Titanium Mesh Electrode is a cheap alternative to pure Platinum Electrodes like Platinum Gauze Electrode or Metal Wire Auxiliary Electrode. Platinum coating makes this counter electrode inert under the reaction conditions and provides catalytic properties. The electrode is installed in the Basic Sample Holder (1 pcs included in the set), which allows full immersion of the electrode in the electrolyte (wet Tantalum contact). It well fits aqueous and organic solvent electrolyte requirements. Electrode size is customizable. 

   

  Application note
  The Platinum Coated Titanium Mesh Electrode is fully immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the Platinum Coated Titanium Mesh Electrode for a certain amount of time. After the process, the electrode should be washed several times with ethanol and dried under the nitrogen flow. Store the electrode in a dedicated compartment to avoid scratching. Discoloration may indicate the degradation (dissolution) of the Platinum layer and oxidation of Titanium mesh. 
  This electrode is used mainly in systems where there is a high risk of its contamination by organic or inorganic deposit during the electrochemical reaction. It is also a cheap replacement for pure Platinum electrode in electrodeposition processes.

   

  Specification
  Titanium grade: GR1
  working current: <5000 A/m²
  Platinum content: >15 g/m²
  Platinum coating thickness: 760 – 1500 nm
  mesh hole size: 3 mm x 2 mm

  Modular PEM Electrolyzer Test Station up to 3 kW (redox.me)

  The Modular PEM Electrolyzer Test Station is a versatile and flexible solution designed for the testing and evaluation of proton exchange membrane (PEM) electrolyzers. Unlike fully automated, integrated systems, this platform features modular components that can be easily swapped by the end user, allowing for customized setups and adaptability to different testing needs. The platform is engineered to provide precise control and measurement of electrochemical performance while offering the convenience of easily replaceable parts.

  This design enables users to test various configurations, integrate new modules, and adapt the system to specific research or development objectives without the need for specialized equipment or extensive downtime. Ideal for research labs and development environments, this platform supports the advancement of PEM electrolyzer technology through hands-on, flexible experimentation.

   

  Application note:
  Ideal for researchers investigating new PEM materials, flow field designs, and cell configurations. The system is an excellent tool for academic institutions and training centers, providing students and researchers with a hands-on understanding of PEM electrolysis processes and system operation. PEM Electrolyzer Test Station with power up to 3 kW is suitable for testing lab-scale or small to medium-scale electrolyzers, typically up to 60 cm². If the power requirements for a given electrolyzer are less than 2 A/cm², larger electrolyzers up to 100 cm² or more can also be tested.
  The entire system, as well as its component parts, are CE certified, which signifies that a product meets European Union (EU) health, safety, and environmental protection standards. Other certificates are available upon request.

  The Modular PEM Electrolyzer Test Station is continuously being improved, so the photos may not fully represent the current version of the device.

  Metal Wire Auxiliary Electrode – 50HX15 0.6/250 mm (redox.me)

  The metal wire counter (auxiliary) electrode is provided in the electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.

   

  Application note
  The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package).
