Compared with conventional oxygen evolution reaction (OER)-paired electrolysis for hydrogen production, ammonia 

oxidation reaction (AOR)-paired alkaline electrolysis off ers enhanced energy effi ciency and reduced costs. AOR-paired 

electrolysis off ers a lower theoretical voltage (0.06 V) compared to the OER (1.23 V), enhancing thermodynamic favorability

owing to its lower theoretical voltage requirements but faces stability and performance challenges. However, 

membrane electrode assembly (MEA) fabrication and operational parameter optimization research related to catalyst 

material development for AOR-paired systems is lacking. In this study, the cell assembly factors, including gasket thickness,

compression forces, thermal conditions, and membrane selection, are analyzed, and the electrolyte concentration and 

electrochemical operating range are optimized for enhanced AOR-paired alkaline electrolysis performance. The optimal 

gasket thickness and assembly pressure improve the electrical conductivity and reduce the contact resistance. Highertemperature

operation and appropriate anion-exchange membrane screening enhance the ionic conductivity and reaction 

kinetics. The optimized KOH/NH 4 OH electrolyte concentration minimizes catalyst poisoning while maintaining high 

catalytic activity. Strategic potential window optimization mitigates irreversible surface poisoning while enabling catalyst 

recovery. Pulsed current protocols eliminate the reverse current phenomenon and electrode degradation by using cyclic 

voltammetry methods. These integrated optimization strategies enhance the current density performance, demonstrating 

the viability of AOR-paired electrolysis for practical hydrogen production applications.
