Magnetic field-enhanced alkaline water electrolysis from laboratory to industry.

ABSTRACT: The fundamental limitation of water oxidation in alkaline water electrolysis (AWE) lies in the progressive depletion of dynamic active sites and rapid dissipation of local active ion concentration, a critical thermodynamic constraint that conventional electrochemical strategies struggle to overcome. Here, we propose a magnetic field-enhanced AWE (ME-AWE) strategy that enables in-situ directional enrichment of local active iron ions near the anode, thus breaking the concentration limit and boosting the coverage of dynamic iron active sites without elevating bulk impurity levels. Laboratory-scale three-electrode experiments confirm improved oxygen evolution reaction (OER) kinetics by the magnetically induced optimization of iron incorporation dynamics and the increase in the coverage
