Transport model for a high temperature, mixed conducting CO2 separation membrane

Strategies and new developments in the field of molten carbonates and high-temperature fuel cells in the carbon cycle

“…These authors used either a DC-powered system with a carbonate electrolyte or directly an MCFC system. Other authors used a composite membrane constituted by a solid oxide phase in contact with a carbonate phase [7]. By one face of the membrane, CO 2 combines with an oxide ion to become CO 3 2À and, at the opposite face, the partial pressure of CO 2 is lower causing a CO 3 2À to drop back into the solid oxide phase:…”

Fast electrochemical CO2 transport through a dense metal-carbonate membrane: A new mechanistic insight

“…The state-of-the-art technologies for carbon capture at power/chemical plants are primarily based on the principles of physiochemical adsorption/ absorption. However, these technologies are expensive, cumbersome and energy intensive [1][2][3][4][5][6][7], making their implementation into the existing plants very difficult. Development of the next-generation cost-effective, energy-efficient and robust carbon capture technologies needs to be urgently pursued.…”

High CO2 permeation flux enabled by highly interconnected three-dimensional ionic channels in selective CO2 separation membranes

“…1(a) at 650 C, [22][23][24] significantly lower than the target value of 1 sccm cm À2 for any potential commercial use. One of the reasons for the low permeance can be ascribed to the ''inefficient'' microstructure containing poorly intra-and interconnected phases that impede ionic transport.…”
