The exchange current density of oxide cathodes in molten carbonates

The exchange current density (i[sub 0]) for oxygen reduction has been measured by using a potential step technique on nonporous oxide electrodes in an Li/K(62/38 mole percent) carbonate eutectic melt at 923 K. Nonporous oxides were fabricated by a hot isostatic pressing method to be as dense as poss...
