| Outline of Final Research Achievements |
Magnesium is one of alternative materials for hydrogen storage since that is abundant and reasonable resource although the high temperature more than 300 °C is needed for nucleating its hydride and dissolving and what is a barrier of the application to automobile and so on. Alloying it to some transition metals might be one of the solutions to improving the property and it has not been got the enough result for the application. It was shown that the three kinds of processing, grinding the crystal grain by mechanical alloying, thinning the film by vacuum deposition and super-layering thin film by cold pressing are effective for better hydrogen absorption and desorption. It was also shown that the activated Knudsen flow developed the amount of hydrogen absorption and desorption for LaNi5 property.
