Abstract
An electrolyzer cell is disclosed which includes a cathode to reduce an oxygen-containing molecule, such as H2O, CO, or a combination thereof, to produce an oxygen ion and a fuel molecule, such as H, CO, or a combination thereof. An electrolyte is coupled to the cathode to transport the oxygen ion to an anode. The anode is coupled to the electrolyte to receive the oxygen ion and produce oxygen gas therewith. In one embodiment, the anode may be fabricated to include an electron-conducting phase having a perovskite crystalline structure or structure similar thereto. This perovskite may have a chemical formula of substantially (Pr(La)(z-y)A'BO(3-∂), wherein 0<x<1, 0≦y≦0.5, and 0.8≦z≦1.1. In another embodiment, the cathode includes an electron-conducting phase that contains nickel oxide intermixed with magnesium oxide.
