| Abstract: | The degradation behavior of hydrogen absorbing kinetics and hydriding dehydriding cycling in different concentration mixed gases(H 2 0 01% CO and H 2 0 1% CO) were investigated. It is shown that the properties of kinetics of MlNi 4.5 Al 0.5 are degraded in hydrogen contatining CO as impurity. The amount of the hydrogen absorbed decreases continuously as the number of cycles is increased under the same concentration of CO. The higher of concentration of CO is, the lower the cycling properties and kinetics for MlNi 4.5 Al 0.5 . The reason for degradation behaviors of MlNi 4.5 Al 0.5 was analyzed. |
