Abstract

Proton-conducting ceramic electrochemical devices were fabricated consisting of a 25-?m-thick BaCe0.2Zr0.7Y0.1O3?? (BCZY27) electrolyte membrane supported on a 1-mm-thick Ni/BCZY27 fuel electrode, and an air electrode consisting of a 40-?m-thick porous \BCZY27\ backbone infiltrated with La2NiO4+? catalyst. Hydrogen flux was measured as a function of gas environment at the air electrode and as a function of applied cell potential and current at 700
