Solid oxide fuel cell components tuned by atomic layer deposition

A reduced cost solid oxide fuel cell having enhanced surface exchange rates and diffusivity of oxide ions comprising:

• a. a first porous electrode and a second porous electrode, wherein said porous electrodes comprise:
• i. a layer of electronically conductive porous non-precious metal, wherein said porous non-precious metal layer is a gas diffusion layer;
• ii. at least one atomic layer of catalytic metal deposited on said non-precious metal layer;
• and
• b. an electrolyte layer disposed between said first porous electrode and said second porous electrode, wherein said electrolyte layer comprises:
• i. a first dense ion-conductive doped oxide film layer;
• and
• ii. a second dense ion-conductive doped oxide film layer deposited on said first doped oxide film layer,
• wherein said catalytic metal layer on said conductive porous non-precious metal layer enhances surface exchange rates and diffusivity of said oxide ions, whereby material costs of said fuel cell are reduced wherein said first dense ion-conductive doped oxide film layer is a semi-porous layer.
