Liquids and rubbery polymers are good candidate membrane materials for the separation of CO{sub 2} from mixtures with H{sub 2} because the solubility selectivity controls the separation that can be obtained. Facilitated transport IEMs containing monopositive ethylene diamine counterions have been shown to be selectively permeable to CO{sub 2} over H{sub 2}. Transport measurements are conducted to determine the influence of feed gas mixture composition, pressure, temperature, and solvent on the CO{sub 2} H{sub 2} permeabilities and separation factor.
