A method for the rapid production of electrode structures such as Cu-SDC anodes for use in direct oxidation solid oxide fuel cells involves co-depositing a copper-containing material and a ceramic by plasma spraying to form a coating on a substrate. Layers of CuO-SDC have been co-deposited by air plasma spraying, followed by in-situ reduction of the CuO to Cu in the anodes. Materials having catalytic properties, such as cobalt, may also be incorporated in the structures. Controlled compositional or microstructural gradients may be applied to optimize the microstructure and composition of the coatings. |
