Redox.me – Photo-Electrochemical H-Cell

Description

This is a horizontally mounted, double compartment photo-electrochemical H-Cell used to simultaneously or individually investigate thin film photo-anode and photo-cathode. The cell elements are made of PEEK and Fluoropolymers. It well fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight having two separate chambers, each equipped with gas inlet and outlet. This allows bubbling the solution and evacuating gases. Chambers are separated with an ion-exchange membrane (e.g. DuPont’s Nafion® membrane), so the electrochemical products appearing at photo-anode and (photo-)cathode do not affect the opposite electrode. Screw mount and hook clamp versions of this cell are available on request. 

Variants

• Water-based electrolyte
• Organic-based electrolyte

Application note
This cell allows several approaches to perform measurements in 2- or 3-electrode setups. It is designed to investigate performance of a thin film photo-anode or photo-cathode (e.g. nanocrystalline material or conducting polymer) deposited on a rigid or flexible transparent substrate (typically fused quartz glass). The counter electrode is mounted in the second chamber either in a top casing or attached on the side of the cell as a thin film deposited on rigid or flexible substrate. The reference electrode is mounted in a top casing of the same chamber as the studied photo-electrode. Various auxiliary electrodes are suitable for this cell including metal wire, gauze and foil electrodes as well as non-metal electrodes and thin films. Typical applications include: basic photochemistry (photo-catalysis), photolytic water splitting, photoinduced charge separation and photo-corrosion. For troubleshooting instruction see the redox.me blog post.
