For the application of fuel cell, the content and concentration of impurities in hydrogen stream must be classified. The purpose of this study is to provide analysis tool for the determination of impurities in hydrogen with ultra high purity. To produce UHT hydrogen, we purified hydrogen gas by both getter-based catridge and liquid-nitrogen soaked catridge. We compare two methods and propose new method to know about what is in hydrogen stream.
