Fuel cells are an efficient, clean alternative to traditional fossil-fuel-based energy systems. Solid oxide fuel cells (SOFCs) are especially attractive due to their ability to use multiple fuels, high efficiency and reversibility. Cobalt (Co)-doped rare-earth layered perovskite oxides are attractive cathode materials for low- and medium-temperature SOFCs. They offer excellent electrochemical performance, owing to their high oxygen content and flexible control of oxygen transport.
