A spacer 130 constituting a cooling passage 160 circulating a cooling medium for cooling the single cells 120 is interposed between adjacent battery modules 110. The spacer 130 has a configuration circulating the cooling medium in the arrangement direction of a single cell case 121 belonging to the battery modules 110. This spacer 130 has a configuration in which a contact area of the cooling medium and the single cell case 121 is larger as it goes to an outlet side from the inlet side of the cooling passage 160. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
