dc.description.abstract | A bilayer configuration of mixed ion-electron conducting La2NiO4+delta and oxygen-ion conducting Gd0.1Ce0.9O1.95 (LNO/GDC10) was proposed for hydrogen production by water-splitting and its properties were measured as a function of temperature, reducing gas CO content and water vapor pressure during the hydrogen production by water-splitting. The hydrogen production flux increased with increasing water vapor pressure and oxygen chemical potential to a maximum of 0.12 cm(3) (STP)/min-cm(2) with 23.25% CO/76.75% CO2 (40 sccm)/balance He (60 sccm) gas mixture on the oxygen-permeate side and wet N-2 (pH(2)O = 0.49 atm) on the oxidizing side at 900 degrees C. The stability of the bilayer membrane was tested in a very low oxygen partial pressure (pO(2)) on the oxygen-permeate side. The presence of GDC10 on the oxygen-permeate side of the bilayer prevented the direct exposure of LNO to very low pO(2) and thus protected it from decomposition, even at pO(2) approximate to 10(-15) atm.
