(Phys.org) —Fuel cells for decentralized energy production require oxygen ion conductors: materials that can store oxygen as ions, and then transport and release it. German researchers have now found an unusual compound that is the first metallic oxygen ion conductor of its kind, as well as the first one that is active at room temperature. As reported in the journal Angewandte Chemie, its activation energy for oxygen ion transport is an order of magnitude lower than that of all previously known materials.
