Description
Xiaogang Sun and co-authors built an anode for splitting seawater into hydrogen that can resist the corrosion seawater causes. Their electrode layers a nickel-iron compound with anions slipped between its sheets. The phosphate version worked best, running for over one thousand hours at high current in a small two-watt alkaline seawater unit.
The team traced the effect to how basic the inserted anions are: strongly basic ones anchor the iron sites and help protons move, lifting both durability and activity. They then scaled up to an industrial one-kilowatt stack. It ran steadily at a current density twice that of a commercial pure-water unit, bringing the hydrogen cost to about one dollar ninety-six per kilogram.
