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

Green Car Congress

The design proved successful in generating hydrogen gas without producing large amounts of harmful byproducts. 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.

Researchers Develop New Lower-Cost, Efficient Catalyst for Water Gas Shift Reaction for Hydrogen Production

Green Car Congress

A team of researchers from Tufts University, the University of Wisconsin-Madison and Harvard University report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H 2 O+CO→ H 2 +CO 2 ) used for producing hydrogen.
