13378FD H Spectroelectrochemical Cell

Product Introduction

The 13378FD H Spectroelectrochemical Cell is designed for electrochemical research combining optical access with controlled electrode reactions. Featuring a chemically resistant PTFE body and a quartz optical window, it supports spectroelectrochemical measurements, catalyst evaluation, and oxygen reduction reaction (ORR) studies.

With a common volume range of 50–250 mL, the cell offers flexible experimental configurations, including gas introduction, proton exchange membrane separation, and customizable left- and right-side arrangements. Its external-thread sealing structure allows 360-degree rotation to align the electrode with the optical window, helping optimize the measurement position.

Performance Features

1. PTFE Cell Body: Provides chemical resistance for a wide range of laboratory electrochemical applications.

2. Quartz Optical Window: Enables optical access for spectroelectrochemical measurements and light-based analysis.

9.Optional Valve: A valve can be added for compatible experimental or chromatography-related configurations.

Working Principle

The 13378FD H Spectroelectrochemical Cell combines electrochemical measurement with optical observation. A potentiostat or electrochemical workstation controls the electrode potential and measures current, while the quartz window provides an optical path for monitoring changes associated with electrode reactions or reaction intermediates.

The working electrode performs the target electrochemical reaction, the counter electrode completes the electrical circuit, and the reference electrode provides a potential reference. Placing the working and reference electrodes in the same chamber can help reduce uncompensated solution resistance when the electrode spacing and electrolyte conductivity are appropriately controlled.

When a proton exchange membrane is installed, it separates the relevant compartments while allowing proton transport under suitable operating conditions. Optional gas introduction supports gas-involving reactions such as oxygen reduction reaction (ORR) research.

How to Select the Right Electrochemical Cell

Choosing an appropriate electrochemical cell is important for obtaining reliable and reproducible experimental results. For oxygen reduction reaction (ORR) testing and other electrochemical studies, consider the following factors.

1. Cell Volume

The electrolyte volume influences mass transfer, solution conditions, and the interaction between the electrode and cell geometry. For rotating disk electrode (RDE) experiments, a sufficiently large cell helps maintain appropriate hydrodynamic conditions and reduces interference from the cell walls.

A volume of approximately 150 mL is often suitable for particular ORR and RDE configurations. Smaller volumes, such as 50–100 mL, may also work, but suitability depends on electrode dimensions, rotation speed, electrolyte properties, and cell geometry.

2. Cell Geometry and Electrode Position

The distance between the working electrode and reference electrode affects uncompensated solution resistance and potential accuracy. A suitable arrangement helps minimize iR drop without disturbing the hydrodynamic conditions around a rotating electrode.

The 13378FD H provides adjustable alignment and a shared chamber for the working and reference electrodes. Electrode placement should be optimized for the specific experiment rather than relying on a universal distance.

3. Optical Window Alignment

For spectroelectrochemical measurements, the electrode and optical window must be aligned to provide a suitable optical path. The 360-degree rotation design helps adjust the relative positioning of the electrode and window.

4. Gas Introduction and Membrane Separation

For gas-involving reactions such as ORR, gas introduction can support controlled reactant delivery. A proton exchange membrane can separate reaction compartments while allowing proton transport. The choice of membrane, gas flow, and electrolyte should match the reaction system and experimental objectives.
