Patent ID: 8354011

Claim:
An electrolyzer cell comprising: a cathode to reduce an oxygen-containing molecule to produce an oxygen ion and a fuel molecule; an electrolyte coupled to the cathode to transport the oxygen ion; an anode coupled to the electrolyte to receive the oxygen ion to produce oxygen gas therewith, the anode comprising an electron-conducting phase comprising a perovskite having a chemical formula of substantially (Pr (1-x) D x ) (z-y) A′ y BO (3-∂) , wherein 0<x<1, 0≦y≦0.5, 0.8≦z≦1.1, D is selected from the group consisting of La, Ba, and a La—Ba mixture, A′ is an alkaline earth metal, and B is a transition metal; and wherein the anode further comprises an ion-conducting phase comprising an oxide.
