Hydrogen Purification by Pressure Swing Adsorption

Abstract

As represented by the launch of fuel cell vehicle (FCV) and the construction of hydrogen fueling station aimed the spread of FCV, the use of hydrogen as a secondary energy is just before the commercialization stage. As a high purity hydrogen is required in this field, the quality of purification technology becomes a very important element. Pressure Swing Adsorption (PSA) is the most practical technology and the purification system (equipment) using PSA technology is most useful on the view of cost performance, simple operation, safe and stability. In this paper, we introduce the history of the development, a principle and application of the PSA.
