PROBLEM TO BE SOLVED: To provide a battery pack absorbing hydrogen gas, restrained from the increase of cost and weight. SOLUTION: A battery pack includes a battery assembly; an exterior case 300 covering the assembly; and a hydrogen storage alloy 400 absorbing the hydrogen gas. The assembly is composed by arranging a plurality of battery cases with a plurality of battery cells 206 housed therein. Each cell 206 respectively includes an exhaust valve 208 for discharging hydrogen gas generated inside the cells 206 to the outside of the cells 206 in the case 300. The alloy 400 is disposed outside the cell 206 inside the case 300. COPYRIGHT: (C)2005,JPO&NCIPI |
