The Advanced Potential Monitoring Flow Cell is a specialized variant of the X-Cell platform, engineered for precise in-situ half-cell potential analysis during electrochemical experiments. This modular cell is designed to integrate seamlessly with external reference electrodes via a Luggin capillary type connection, allowing researchers to accurately decouple the performance of the anode and cathode in complex systems like AEMWE, PEM, and CO₂ reduction.
