| Outline of Final Research Achievements |
In this study, we have developed hydrogen selective gas separation membranes which can be used for the separation of hydrogen over oxygen in an atmospheric temperature and pressure. The goal performance was the separation factor of 100 and the hydrogen permeance of 100 [1E-10 mol/(m2 s Pa)]. We selected three kind of membrane materials: a crosslinked polyimide, a carbon prepared from Kapton polyimide, and a silica to fabricate composite hydrogen selective membranes. The highest performance of the membrane prepared from each material is as follow. The separation factor and hydrogen permeance are 77 and 6 for the crosslinked polyimide membrane, 26 and 35 for the carbon membrane, respectively. Hydrogen selective silica membrane was not successfully fabricated. The performance for crosslinked polyimide and carbon membranes may be improved to some extent by optimizing fabrication conditions.
