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. 

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.
