While a Japanese team developed a series of Er(Ho)Co2-based magnetic cooling alloys for hydrogen cooling, a US research team used a "simple" acid treatment to increase flow of hydrogen atoms within protonic ceramic electrochemical cells (PCECs). Hydrogen-fuelled mobility registered significant developments: the first hydrogen-electric passenger aircraft was piloted between two major airports in Germany, and a 75-passenger ferry service in the San Francisco Bay braces for operations in June.National Institute for Materials Science (NIMS), Tohoku University and Japan Synchrotron Radiation Research ...Den vollständigen Artikel lesen ...
