Full Article:

Standard electrolyte materials (ceramic oxide-ion conductors and eutectic mixtures of alkaline carbonates) used in Solid Oxide and Molten Carbonate Fuel Cell technologies can be combined to produce composite CO2 separation membranes for a variety of applications. The model performance of these membranes is reviewed highlighting critical design and performance parameters. This model is used to build diagrams where actual membrane permeation data can be benchmarked against an ideal performance, providing immediate guidance on likely kinetic limitations. A complementary pictorial tool is also described to assess the electrical microstructure of these composites before permeation tests. The added value from combination of such diagrams in process control or membrane development is discussed.
