Abstract
Most studies on ammonia electrolysis have focused on anion exchange membranes (AEMs), which face limitations in operating conditions, such as pH and ammonia concentration. This study introduces a novel concept of an ammonia electrolysis cell (AEC) utilizing a Zirfon separator capable of operating under high pH and ammonia concentrations. The Zirfon-based AECs achieve a peak current density of 915 mA cm(-2), representing the highest reported value in AEC literature. Additionally, the Zirfon separator exhibits less conductivity degradation than AEMs during cycling tests (Zirfon 14.1%, AEMs 30.2%), demonstrating superior durability of the Zirfon-based AEC.
