Researchers devise seawater-resilient bipolar membrane electrolyzer for turning seawater into hydrogen

Green Car Congress

Generation of H 2 and O 2 from untreated water sources represents a promising alternative to ultrapure water required in contemporary proton exchange membrane-based electrolysis. Next, the team plans to improve their electrodes and membranes by building them with materials that are more abundant and easily mined.
