Scientists have made a discovery that could dramatically improve the efficiency of batteries and fuel cells. The research involves improving the transport of oxygen ions, a key component in converting chemical energy into electricity. The team studied a well-known material, gadolinium doped ceria (GDC), which transports oxygen ions and is currently in use as a solid oxide fuel cell electrolyte.
Through the use of additives and a "smart" chemical reaction, they demonstrated a greatly enhanced conductivity in GDC. The result is a faster and more efficient conversion into electricity.Image credit: iStock
