| Abstract | Summary form only given, as follows. The investigations of hydrogen desorption from reversible hydrides of intermetallic compounds have shown that this process is accomplished with the presence of non equilibrium concentration of vibrationally-excited and charged particles. In this case the hydrogen desorbed from metal-hydrides can be ionized more easily than the conventional molecular hydrogen from the reservoir. It is shown that the ionization cross section is 50% higher and the ionization potential is 0.5 eV lower for desorbed hydrogen, than for reservoir gas. The glow discharge ignition in hydrogen, deserbed from metalhydride, takes place for the lower value of electrodes potential. In this paper the results of the experimental investigations of characteristics of glow discharge with metal-hydride alloy (Zn-V-Fe)H/sub X/ electrodes are represented. Gas pressure in the chamber was changing from 1 to 10 Torr. The discharge voltage was (300-350) V. The metal-hydride element, which was installed in gas discharge chamber, was 2 cm diameter disk made of a composite material, containing a hydrogenated zirconium alloy mixed with a bonding agent (copper). During the hydrogen desorption from metalhydride for the positive potential of this electrode, the discharge current was 30% higher than that in the case of reservoir hydrogen, and for the negative potential the discharge current was 10-15 times higher. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
