Described herein are solid oxide fuel cells comprising conductive layers and methods of fabricating such cells. Specifically, a solid oxide fuel cell comprises cathode and anode layers, each comprising a porous base, catalyst sites disposed within the base, and a conductive layer. The conductive layer provides electrical conduction between the corresponding current collector and the catalyst sites. The conductive layer may at least partially extend into the porous base. For example, at least a portion of the conductive layer may be formed by infiltration of the porous base, e.g., before catalyst infiltration. In some examples, at least a portion of the conductive layer forms an interface between the corresponding porous base and the current collector. In these examples, the conductive layer is formed from an initial (green) conductive layer that is stacked between layers used to form the porous base and current collector and sintered the stack.
