    Abstract: A redox ion exchange membrane may include an electrically-conductive material; and redox-active materials associated with that material, the redox-active materials having reversible oxidation and reduction properties. The redox-active materials may be inorganic nanostructures on the electrically-conductive material. A hydrogen production device and a fuel cell device may include such a redox ion exchange membrane positioned between the cathode and anode. A method of producing hydrogen gas may include providing a cathode, an anode, and a redox ion exchange membrane positioned between the cathode and the anode, and applying electrical power to the cathode and the anode; where that applying causes simultaneous reciprocal reduction and oxidation reactions on opposite sides of the redox ion exchange membrane, such that H+ is released on one side of the redox ion exchange membrane

    Abstract: 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.
