Gas diffusion electrode testing device

This product is developed for evaluating gas diffusion electrodes in a three-electrode configuration, supporting research on electrochemical reactions involving gaseous reactants. With a cell volume of approximately 10 mL and an integrated gas flow path measuring 18 mm × 18 mm, it enables controlled exposure of the working electrode’s active area (8 mm diameter) while allowing user-selected counter and reference electrodes. The default setup includes a silver chloride reference electrode and a platinum wire counter electrode, providing a ready-to-use platform for catalyst screening, fuel cell, or electrolyzer studies. Its compact, well-defined reaction zone and gas-flow integration make it suitable for reliable, reproducible half-cell testing in energy materials research.
