| Research Abstract |
The novel H2 separation membrane with 100% selectivity is proposed based on a dual-phase mixed H+-e- mixed conductor. The membrane consists of Nafion as a proton (H+) conductor and carbon as an electronic conductor, and each phase forms interconnecting network to make the trans-membrane H+ and e- conduction possible. The H2 separation performance increased with increases in the volume fraction of Nafion in the composite film, in three-phase boundary among Pt catalyst, membrane and H2 gas, and in humidity of ambient ambient atmosphere. By fine-tuning those parameters, it has been succeeded to fabricate the membrane with the permeation flux of 0.7 mL min-1 m2.
