Fig. 2: Electrochemical performance and durability of seawater electrolysis with ISG.
From: Ion-selective interface engineering for durable electrolysis of impure water
a Schematic of the electrolyzer using natural seawater for electrolysis with ISG at both electrodes to regulate ion transport and pH. b The volume ratio of hydrogen to oxygen during long-term seawater electrolysis. c Electrolysis durability test at a constant current density of 200 mA cm−2 in Henley Beach seawater, showing stable voltage operation over 1500 h with ISG, compared to rapid voltage increases without ISG. Inset table summarizes the operating parameters used in this work. d Active chlorine concentration and relative Faradaic efficiency for hydrogen production in seawater electrolysis.
