Patent ID: 8026014

Claim:
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.
