This study aims to establish hydrogen storage and supply system for residence. We devised new hydrogen system without heat exchange to supply and store hydrogen, which has better energy efficiency than conventional hydrogen storage system. Firstly, hydrogen absorbing alloys were selected as a hydrogen storage material which is easy to handle (no heat exchange) and safer to use (at normal pressure).Characteristics of hydrogen supply and storage were examined by an experiment. Secondly, basic hydrogen supply and storage performance tests of the system were conducted. Finally, the hydrogen powered fuel cell was operated by the system to determine duration time of constant hydrogen supply. The results suggested that the system can operate hydrogen powered fuel cell at normal temperature and pressure.
