NOVELTY - The solid oxide fuel cell comprises first and second porous electrodes (110), and an electrolyte layer (102) disposed between the first and second porous electrodes. The porous electrodes comprise a layer of electronically conductive porous non-precious metal, and an atomic layer of catalytic metal (114) deposited on the nonprecious metal layer. The porous non-precious metal layer is a gas diffusion layer. The electrolyte layer comprises a first dense ion-conductive doped oxide film layer, and a second dense ion-conductive doped oxide film layer deposited on the first doped oxide film layer.    USE - Used as a solid oxide fuel cell.    ADVANTAGE - The solid oxide fuel cell can be cost-effectively manufactured, and has enhanced surface exchange rates and diffusivity of oxide ions and high efficiency and fuel flexibility.    DETAILED DESCRIPTION - The solid oxide fuel cell comprises first and second porous electrodes (110), and an electrolyte layer (102) disposed between the first and second porous electrodes. The porous electrodes comprise a layer of electronically conductive porous non-precious metal, and an atomic layer of catalytic metal (114) deposited on the nonprecious metal layer. The porous non-precious metal layer is a gas diffusion layer. The electrolyte layer comprises a first dense ion-conductive doped oxide film layer, and a second dense ion-conductive doped oxide film layer deposited on the first doped oxide film layer. The catalytic metal layer on the conductive porous non-metal layer enhances surface exchange rates and diffusivity of the oxide ions. The non-precious metal layer is applied by a growth method such as sputtering, evaporation, electroplating, pulsed laser deposition, chemical vapor deposition or atomic layer deposition. The precious metal layer is an atomic layer deposition layer, which provides enhanced surface electrochemical reaction during fuel cell operation. The ion-conductive doped oxide film layers have a thickness of 10 nm to 10 mu m, and are mechanically stable to be freestanding. The second dense ionconductive doped oxide film layer is different from the first dense ionconductive doped oxide film layer, which is a semi-porous layer.
