a Schematic of the AEM electrolyzer components and H2 production by the AEM electrolyzer in alkaline seawater. b Photograph of the AEM electrolyzer. c Polarization curves normalized by the electrode area of RuMoNi || RuMoNi in 1.0 M KOH + seawater at 20 °C and 6.0 M KOH + seawater at 60 °C with RuO2 || Pt/C as a comparison. d Durability test of the AEM electrolyzer using RuMoNi || RuMoNi at 500 mA cm−2 in a 1.0 M KOH + seawater electrolyte. e Comprehensive comparison of the performance of the electrolyzer catalyzed by RuMoNi || RuMoNi with reported seawater AEM electrolyzers in a radar chart whose axes have different meanings and units (see Supplementary Table 8 for the references where the specific values of NiFe LDH, Ni-doped FeOOH, and Fe,P-NiSe2 are reported).
