Berkeley Lab Scientists Achieve Breakthrough in Nanocomposite for High-Capacity Hydrogen Storage

Berkeley Lab researchers have designed a new composite material for hydrogen storage consisting of nanoparticles of magnesium metal sprinkled through a polymer related to Plexiglas that rapidly absorbs and releases hydrogen at modest temperatures without oxidizing the metal after cycling. This achievement is a major breakthrough in materials design for hydrogen storage, batteries and fuel cells.

Fuel Cells in Operation: A Closer Look

Watching the components of a fuel cell work together under heat and pressure is a challenge, because the best technique, x-ray photoelectron spectroscopy (XPS), can only be used in a vacuum—until now, that is. A working solid oxide electrochemical device operating at 750 degrees Celsius has been studied in detail for the first time by scientists working at the Advanced Light Source, using a new ambient pressure XPS system invented at Berkeley Lab.
