<p><P>PROBLEM TO BE SOLVED: To improve temperature distribution in the center axis direction of cell structures and uniformity of temperature distribution of the cell structures in which a plurality of unit cells are connected in series. <P>SOLUTION: First to fourth nearly plate-like separators 15a, 15b, 15c, 15d are arranged in respective upstream and downstream parts of the two battery modules deployed in the direction of the cooling air circulation. A plurality of flow holes 31 which are installed at respective separators 15a, 15b, 15c, 15d so as to face the outer circumferential faces are installed in a prescribed spacing L along the direction in parallel with the center axis P of a battery structure 22. At respective separators 15a, 15b, 15c, 15d, rectifier members 32 are installed protruding at a tilting angleθagainst the center axis P of the battery structure 22 going into the interior of respective flow holes 31 for smoothly standing in a row from the inner peripheral faces 31A of the respective flow holes 31 provided at the separator main bodies. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
