Fig. 4: EA operation with other electrodes.

a Potential traces of Ni foam, SS felt, Co foam, and Fe foam at 0.5 A cm–2 with and w/o EA operation in unpurified 1 M KOH solutions. b Overpotential difference at 0.5 A cm–2 after 50 h between operations with (η50h EA) and w/o EA (η50h w/o EA). Error bars indicate standard errors obtained from 3 or more independent replicates.
