Flow Electrochemical H-Cell setup
This is a horizontally mounted, double compartment electrochemical flow H-Cell. The cell elements are made of PEEK. It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight having two separate chambers, each equipped with electrolyte inlet and outlet. This allows filling up the cell with an electrolyte (static mode) or circulation of the electrolyte (flow mode). Chambers are separated with an ion-exchange membrane (e.g. DuPont’s Nafion® membrane), so the electrochemical products appearing at working and counter electrode do not affect the opposite electrode. Each chamber is able to accommodate three electrodes.
This cell allows several approaches to perform measurements in 2- or 3-electrode setups. It is designed to investigate the performance of a material (e.g. nanocrystalline material or conducting polymer) deposited on a working disk electrode. The metal wire counter electrode is mounted in the second chamber, while the reference electrode is mounted in the same chamber as the working electrode. Various counter electrodes are suitable for this cell including metal wire, as well as non-metal electrodes such as graphite rod. Typical applications include: basic electrochemistry, long-term measurements, RE potential measurements as well as electrosynthesis. For troubleshooting instruction see the redox.me blog post.
