Resumen
Iron oxides as materials for fuel cell electrodes and high-temperature electrolysers. The development of high-performance materials at relatively low temperatures (700°C) for SOFC (Solid Oxide Fuel Cell) electrodes and SOEC (Solid Oxide Electrolysis Cell) electrolysers based on non-critical elements is one of the most important and urgent challenges facing the technological advancement of these devices for the use and production of "green" hydrogen. The present invention proposes new oxides based on Fe doped with Ni and Cu that present high electrocatalytic activity in air and at 700°C, which places them as potential oxygen electrodes, both for SOFC fuel cells (cathodes) and for SOEC electrolysers (anodes), as well as their method of obtaining.
