H₂ is an important industrial gas, and high purity H₂ is required for applications. Recent advances in both H₂-selective and CO₂-selective membranes for H₂ purification are reviewed with an emphasis on the development of CO₂-selective facilitated transport membranes for H₂ purification. With CO₂-selective facilitated transport membranes, examples of high-pressure and low-pressure H₂ purification applications are discussed. In high-pressure H₂ purification in the Integrated Gasification Combined Cycle (IGCC) operation, experimental and modeling results demonstrated the potential of amine-containing facilitated transport membranes to achieve an economically attractive cost of electricity. CO₂-selective membranes for low-pressure H₂ purification for fuel cells have been developed for both PEMFC and SOFC. The membranes have been scaled-up, and they have shown promising gas transport performances for the respective applications.
