a Cathodic stability and H2 coevolutionary behavior of the magnetized ZnSO4 electrolyte determined by LSV. b O2 coevolution behavior of the magnetized ZnSO4 electrolyte determined by LSV. The measurements were performed in a three-electrode cell consisting of a Pt foil working electrode, a Zn counter electrode, and an Ag/AgCl reference electrode at a scan rate of 1 mV s−1 at ~298 K. c Schematic illustration of proton transport via the Grotthuss mechanism in the ZnSO4 electrolyte. d Schematic illustration of the transport limitation for protons and water in the magnetized ZnSO4 electrolyte.
