| Outline of Final Research Achievements |
The goal of this research is to develop a novel device for separating hydrogen gas utilizing the Soret effect, which produces a concentration difference only by imposing a temperature difference. In our experiment, the mixture gas of hydrogen and carbon dioxide was passed through a micro channel, in which temperature difference was imposed in the direction crossing the flow normally. In the first two years, we built a special device with silicon wafer and glass by MEMS fabrication technology, and imposed temperature difference of 80 Centigrade. With two-step separation, we obtained 0.8 % of hydrogen increment. In the last year, to enhance separation by increasing temperature difference, we remade the micro device by using stainless steel. With temperature difference of 300 Centigrade, and with three-step separation, we obtained 1.22 % increment of hydrogen concentration. We confirmed the validity of application of the Soret effect and multi-process to hydrogen separation.
