Outline of Final Research Achievements

In order to transition to a hydrogen-based clean energy society in the future, it is necessary to develop new hydrogen refining technologies. This study addressed this issue. In other words, unlike conventional hydrogen purification methods using hydrogen separation membranes, we have developed a new hydrogen purification technology and process that utilizes the gas permeation characteristics of the fabricated polymer membrane.
First, separation membranes made of two types of polymers were fabricated. That is, (1) a membrane capable of preferentially permeating diffusion gas such as H2 and He and (2) a membrane capable of preferentially permeating CO2 were prepared. We proposed a separation technology and process that successfully combines the features of these membranes, and conducted a basic evaluation study. As a result, a new hydrogen purification process with high efficiency was developed.
