The CO2 permeance across the YSZ-molten carbonate dual-phase membrane was observed to be higher than 0.1 x 10(-8) mol/m(2)/Pa/s at temperature >650 degrees C. The movement of ions was promoted at high temperature as YSZ and molten carbonate became highly conductive to oxygen ions and carbonate species, respectively. Addition of poly(methyl methacrylate) (PMMA) during preparation of macroporous YSZ support created interconnected pore structures that were found conducive for carbonate infiltration and integration with the membrane materials.
