This is a horizontally mounted, double compartment, screw mount photo-electrochemical H-Cell used to simultaneously investigate thin film photo-anodes and (photo)cathodes. The cell elements are made of PEEK. It well fits aqueous (EPDM/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. Magnetic mount version of this cell is available here. 

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 (e.g. nanocrystalline material or conducting polymer) deposited on a rigid or flexible transparent substrate (typically fused quartz glass). The cathode (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 photo-anode. 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, photolytic water splitting, photoinduced charge separation and photocorrosion. For troubleshooting instruction see the redox.me blog post.
