| Abstract Scope |
Electrofuels produced using renewable energy are the desired energy carrier for a carbon-free society. Iron powder produced electrolytically from iron oxide is an Electrofuel having high-energy density. They can be combusted to their oxide to release the chemical energy at different scales comparable to fossil fuels but without the harmful emissions. In this work we investigate a novel method of electrolytically reducing the iron oxide back to iron employing solid oxygen-ion conducting membrane (SOM) cell with liquid silver as the reducing medium. Liquid silver with the iron oxide is contained in the SOM cell, and the soluble oxygen is pumped out of liquid silver with a system of electrodes to generate the required reducing conditions. Since iron and liquid silver have no mutual solubility, the reduced iron is easily separated employing magnetic means. Details regarding cell design, electrode choices, and product characterization will be presented along with cell performance. |
