    摘要: An electrolyzer cell (100) is disclosed which includes a cathode (104) to reduce an oxygen-containing molecule, such as H2O, CO2, or a combination thereof, to produce an oxygen ion and a fuel molecule, such as H2, CO, or a combination thereof. An electrolyte (106) is coupled to the cathode (104) to transport the oxygen ion to an anode (102). The anode (102) is coupled to the electrolyte (106) to receive the oxygen ion and produce oxygen gas therewith. In one embodiment, the anode (102) 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(1-x)Lax)(z-y)A'yBO(3-∂), wherein 0≤x≤ 0.5,0≤y ≤ 0.5, and 0.8≤z≤1.1. In another embodiment, the cathode (104) includes an electron-conducting phase that contains nickel oxide intermixed with magnesium oxide.
