| Research Abstract |
For implementation of hydrogen society, development of high volume efficient and high durability hydrogen storage method is the most urgent issue. Hydrogen (protium)storage alloys are known for its volume efficiency but their poor desorption characteristics at cold temperature and durability should be improved. Through this research, V-rich V-Ti-Cr-M(M=Al, Mo)with high effective cyclic protium capacity (about 2. 3mass%), high durability (maintaining 99%of initial capacity after 200 cycles)and good hydrogen de sorption characteristics (0. 2Mpa at-30degree Celsius). These alloys are holding state of the art performance as of Fy2011.
